### TL;DR: Best Calendar Apps for Windows in 2027

Windows no longer has its own calendar app. Microsoft retired Mail and Calendar at the end of 2024 and replaced it with the new Outlook, which is our top pick if you use Microsoft 365 or Outlook.com. Gmail users are best served by Google Calendar, although it only runs in the browser. For a native desktop app with power-user features, Fantastical is our pick, and One Calendar and Wino Mail & Calendar are good free options. If you plan your day by putting tasks on your calendar, Morgen and Akiflow are built for that.

If you've used a Windows PC for a while, you probably remember the Calendar app that came with it. Microsoft ended support for Windows Mail and Calendar on December 31, 2024. It no longer syncs, and Microsoft now points everyone to the new Outlook instead. That's fine if your work already runs on Microsoft 365, but less so if your life is in Gmail, iCloud or a mix of all three.

So what's the **best calendar app for Windows** now? We looked at the built-in option, the big web calendars and the desktop apps that have stepped into the gap, and picked ten that are worth your time, plus two extras that fix specific Windows annoyances. You'll find what each one is best for, which accounts it connects to, whether it's a real desktop app or a browser tab, and what it costs.

A calendar only helps if you trust it enough to [plan your time](https://timingapp.com/blog/time-well-spent/) around it, so pick one you'll actually open every day. On a Mac? Read our guide to the [best calendar apps for Mac](https://timingapp.com/blog/best-calendar-apps-for-mac/) instead.

## Does Windows Still Have a Calendar App?

No. Microsoft retired the Windows Mail and Calendar app on December 31, 2024, and the calendar on Windows now lives in the new Outlook. Here's what changed, and why it matters when you choose a replacement:

- **Mail and Calendar is gone.** Microsoft stopped supporting the old Windows Mail and Calendar app on December 31, 2024. Its replacement is the new Outlook for Windows, which handles email and calendar in one app.
- **The new Outlook is free, with conditions.** Without a Microsoft 365 subscription, it shows ads. Microsoft also lists offline calendar access in the new Outlook as only partly available, so it's less useful on a flight or a patchy connection than the old app was.
- **Google Calendar has no Windows app.** It runs in a browser. You can use it offline in Chrome, but only to view events, not to create or change them.
- **The taskbar clock shows no events.** Windows 10 showed your agenda when you clicked the clock. Windows 11 doesn't. Microsoft announced an agenda view for the Windows 11 taskbar in November 2025, then delayed it in March 2026, and it hadn't reached Windows 11 users when we checked in October 2026.

That leaves you with three kinds of calendar apps on Windows: Outlook, browser-based calendars, and third-party desktop apps that connect to the accounts you already have. All three are in our list.

## What to Look for in a Calendar App for Windows

Keep these points in mind as you compare your options:

- **Your accounts:** Check that the app connects to every calendar you use. Microsoft 365 and Exchange work accounts are the most common sticking point. Not every app supports them, and some workplaces have to approve third-party apps before you can sign in.
- **Desktop app or browser tab:** A desktop app opens from the Start menu, sends proper Windows notifications and often works offline. A web calendar saved as an app from Chrome or Edge gets you part of the way there.
- **Offline access:** If you work on the move, check what the app can do without a connection. Some only let you view events offline, and a few let you edit them too.
- **Quick access:** Windows 11 doesn't show your agenda on the taskbar, so a mini window in the system tray (or a small add-on) saves you opening the full app all day.
- **Tasks and planning:** If you like to [time block](https://timingapp.com/blog/time-blocking/) your day, look for an app that can put tasks from your to-do list onto your calendar.
- **Scheduling:** Booking links and availability sharing save a lot of back-and-forth emails if you meet with clients or people outside your company.

## The Best Calendar Apps for Windows in 2027: Comparison Table

We reviewed a wide range of calendar apps for Windows against the criteria above, looking at how well each one handles Microsoft, Google and iCloud accounts, whether it's a desktop app, how it works offline, and whether it's actively maintained. Here's how our ten picks compare:

Pricing correct as of November 2026. Ratings are from the US Microsoft Store, or from G2 or Capterra for apps that aren't in the Store.

## The 10 Best Calendar Apps for Windows

### 1. [Outlook](https://www.microsoft.com/en-us/microsoft-365/outlook/email-and-calendar-software-microsoft-outlook)

![Week view in the new Outlook for Windows with work events and a calendar list](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-outlook.jpg)

*Image:* [*Microsoft*](https://apps.microsoft.com/detail/9NRX63209R7B?hl=en-US&gl=US)

**Best for:** Anyone whose work runs on Microsoft 365, and anyone who wants the calendar Microsoft now offers with Windows.

The new Outlook for Windows is Microsoft's replacement for Mail and Calendar, so it's the first calendar most Windows users meet. It also keeps email and calendar in one window. When you set up a meeting, the Scheduling Assistant shows when colleagues are free, and you can add a Teams link with one click. For anyone on a Microsoft 365 work account, nothing else on this list fits in as smoothly with shared calendars, Teams and the rest of Microsoft's tools.

It isn't only for Microsoft accounts. The new Outlook also connects Gmail and Yahoo accounts and syncs their calendars.

There are trade-offs. Without a Microsoft 365 subscription, the free version shows ads, and Microsoft lists offline calendar access in the new Outlook as only partly available. If you rely on your calendar without a connection, test it before you commit.

**Pricing:** [The new Outlook](https://www.microsoft.com/en-us/microsoft-365/buy/compare-all-microsoft-365-products) is free with ads. Microsoft 365 Personal removes the ads and costs $9.99 per month or $99.99 per year. Microsoft 365 Family covers up to six people for $12.99 per month or $129.99 per year. Work accounts come with Microsoft 365 business plans, which are priced per user. Prices shown are Microsoft's US prices in USD. Microsoft 365 prices vary by country, so you may see different amounts on Microsoft's site.

### 2. [Google Calendar](https://calendar.google.com/)

![Google Calendar in a web browser, week view with the new-event dialog open](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-google-calendar.png)

*Image:* [*Google*](https://workspaceupdates.googleblog.com/2024/10/new-look-and-feel-and-dark-mode-google-calendar.html)

**Best for:** Gmail and Google Workspace users who want their calendar to work everywhere.

Google Calendar is free, familiar and works the same on any computer with a browser. It turns flight and restaurant bookings from Gmail into events, adds Google Meet links to invitations, and makes it easy to check colleagues' availability. Appointment schedules let people book time with you through a link, and on most paid Google Workspace plans, Time Insights shows how much of your week goes into meetings (our guide to [Google Calendar Time Insights](https://timingapp.com/blog/google-calendar-time-insights/) explains how to use it).

On Windows, though, Google Calendar is a website, not an app. In fact, Google doesn't make a desktop version. The closest you'll get is installing the site as an app from Chrome or Edge, which gives it its own window and a spot on your taskbar. Offline use is limited: in Chrome, you can view your events without a connection, but you can't create or change them, and Google doesn't support offline mode in Edge.

If you'd rather have Google Calendar in a real desktop app, most of the third-party apps below connect to Google accounts. The new Outlook does too.

**Pricing:** [Google Calendar](https://calendar.google.com/) is free with a Google account. Businesses can get it as part of Google Workspace, which is priced per user.

### 3. [Fantastical](https://flexibits.com/fantastical)

![Fantastical for Windows showing a quarter view with weather](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-fantastical.png)

*Image:* [*Flexibits*](https://flexibits.com/blog/2024/10/fantastical-for-windows-is-finally-here/)

**Best for:** Power users who want to type events in plain English and see every account in one polished app.

Fantastical spent years as a Mac and iPhone favorite before Flexibits brought it to Windows in October 2024. It's one of the most capable third-party calendar apps on Windows, and it's actively developed: [Fantastical 4.2 for Windows](https://flexibits.com/fantastical-windows/releasenotes) came out on October 5, 2026.

Where Fantastical stands out is how fast you can add things. Type "Lunch with Sam Friday at 1pm" and Fantastical builds the event for you, or start with "remind me to" and it creates a task instead. A mini window opens from the system tray, which goes some way toward making up for the missing taskbar agenda. You also get day, week, month, quarter and year views, weather forecasts, and tasks from Todoist and Google Tasks alongside your events.

Many of the features power users want are part of Flexibits Premium, including video call links for Zoom, Teams, Meet and Webex, calendar sets, event templates, and Fantastical's scheduling tools. With Openings and Proposals, you can share your availability or offer several meeting times and let people pick.

However, the Windows version has far fewer Store ratings than the Mac app, and a lower score.

**Pricing:** [Fantastical](https://flexibits.com/pricing) has a free version for basic events. Flexibits Premium covers Fantastical on every platform it supports, so one subscription works on both a Windows PC and an iPhone. The Individual plan costs $4.75 per month and the Family plan, for up to five people, costs $7.50 per month, both billed annually. There's also a Team plan for $4.75 per user per month, billed annually. Prices shown are Fantastical's US prices in USD. Fantastical's pricing varies by country, so you may see different amounts on its pricing page.

### 4. [eM Client](https://www.emclient.com/)

![eM Client for Windows calendar in month view with two accounts](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-em-client.png)

*Image:* [*eM Client*](https://apps.microsoft.com/detail/9NM8S4PVF0N2?hl=en-US&gl=US)

**Best for:** People who want a full desktop email and calendar app that isn't Outlook.

eM Client is a Windows desktop app for email, calendar, tasks and contacts, from a Czech company that has been making it for well over a decade. If you liked the all-in-one approach of classic Outlook but don't want to move to the new Outlook, it's the closest alternative.

The calendar connects to Microsoft 365, Outlook.com, Google and iCloud accounts. [eM Client 11](https://www.emclient.com/release-history), released on October 8, 2026, added support for Microsoft's newer Graph connection for Microsoft 365 accounts, multiple reminders per event and multiple time zones. In addition, a sidebar keeps your agenda next to your inbox, and you can see an event's organizer at a glance.

The interface is dense, with a lot of toolbar buttons, so it takes a little longer to learn than the lighter apps on this list. Its Microsoft Store rating is middling, too, so read a few recent reviews before you buy.

**Pricing:** [eM Client](https://www.emclient.com/pricing) is free for home use on one device with up to two email accounts. eM Client Personal, for one person on up to three devices, costs $24.95 per year or $39.95 one-time. The Business license costs $29.95 per year or $44.95 one-time, per device.

### 5. [One Calendar](https://www.onecalendar.nl/)

![One Calendar for Windows month view with week numbers](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-one-calendar.jpg)

*Image:* [*One Calendar*](https://apps.microsoft.com/detail/9WZDNCRDR0SF?hl=en-US&gl=US)

**Best for:** Anyone who wants all their calendars in one free Windows app, without ads.

One Calendar, from Dutch developer Code Spark, is a long-standing favorite in the Microsoft Store, and it's easy to see why. The free version connects an unlimited number of accounts from almost any provider: Google, Outlook.com, Microsoft 365, Exchange, iCloud, Yahoo and any CalDAV calendar, including Nextcloud and Synology. It works offline, shows no ads, and gives you list, day, week, month and year views.

However, it's a straightforward calendar rather than a planning tool. There's no natural language entry, task scheduling or booking links, and the design looks a few years old next to Fantastical or Wino. If you just want to see your work and personal calendars side by side on a Windows PC and add the odd event, that's not a problem.

One Calendar is also available for Mac, iPhone, iPad and Android.

**Pricing:** [One Calendar](https://apps.microsoft.com/detail/9WZDNCRDR0SF?hl=en-US&gl=US) is free. The Premium version is a $5.99 one-time in-app purchase and adds search, printing, themes, custom event colors and faster syncing. Prices shown are Microsoft Store US prices in USD. Microsoft Store prices vary by country, so you may see different amounts in the Store.

### 6. [Wino Mail & Calendar](https://www.winomail.app/)

![Wino Calendar for Windows week view in dark mode](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-wino.jpg)

*Image:* [*Wino Mail*](https://apps.microsoft.com/detail/9NCRCVJC50WL?hl=en-US&gl=US)

**Best for:** Former Windows Mail and Calendar users who want something that looks and feels like it.

Wino was built to fill the gap Microsoft left. It's a fast, native Windows app for mail, calendar, contacts and to-dos, designed in the style of Windows 11 and in the spirit of the old Mail and Calendar app. Switching between mail and calendar is instant, and it starts quickly and uses little memory compared with web-based apps.

The calendar syncs with Outlook, Google and CalDAV accounts. You can create and edit events and recurring series, set reminders and respond to invitations, and it keeps working offline. Finally, themes, including a theme editor, let you make it look the way you want.

Wino is an open-source project from one indie developer, Burak Kaan Köse, who has been building it since 2021. It's actively maintained: [version 2.2.7](https://github.com/bkaankose/Wino-Mail/releases) came out on October 25, 2026. It doesn't have the support team of a large company behind it, but it has an active open-source community on GitHub.

**Pricing:** [Wino Mail & Calendar](https://apps.microsoft.com/detail/9NCRCVJC50WL?hl=en-US&gl=US) is free. An Unlimited Accounts add-on costs $9.99 one-time and removes the limit on the number of accounts you can connect. Prices shown are Microsoft Store US prices in USD. Microsoft Store prices vary by country, so you may see different amounts in the Store.

### 7. [Notion Calendar](https://www.notion.com/product/calendar)

![Notion Calendar’s three-day view with the month overview and calendar list in the sidebar](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-notion-calendar-window.png)

*Image:* [*Notion*](https://www.notion.com/product/calendar)

**Best for:** Notion users who want their calendar and their notes in the same place.

Notion Calendar is a free, keyboard-first calendar that grew out of Cron, a calendar app Notion bought in 2022. The Windows app is a direct download from Notion rather than a Microsoft Store app. It connects to Google, Outlook and iCloud accounts, and it's quick to use once you learn the shortcuts. A command bar lets you jump to a date, create an event or switch views without touching the mouse.

The real draw is the link to Notion. For example, dates from your Notion databases can appear on your calendar, so project deadlines sit next to your meetings. A Share availability panel lets you send open time slots to someone without a separate scheduling tool.

If you don't use Notion, most of that advantage disappears, and the free apps above give you more for a plain calendar. Also note that Notion Calendar's iPhone and Android apps don't support Outlook calendars as of October 2026, so it's a weaker fit if you need your Outlook calendar on your phone.

**Pricing:** [Notion Calendar](https://www.notion.com/product/calendar) is free.

### 8. [Morgen](https://www.morgen.so/)

![Morgen calendar with a task list from several apps next to the week view](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-morgen.jpg)

*Image:* [*Morgen*](https://www.morgen.so/)

**Best for:** Time blocking tasks from your to-do app straight onto your calendar.

Morgen combines your calendars and your tasks in one view, so you can plan your day by dragging to-dos into free time. It's built around [block scheduling](https://timingapp.com/blog/block-schedule/), the idea that work you haven't given a time slot is work that probably won't happen.

Morgen's Windows app runs on 64-bit Windows 10 and 11. It connects to more kinds of calendars than most planners, including Google, Outlook, iCloud, Fastmail and any CalDAV account. On the task side, it pulls in to-dos from Todoist, Notion, ClickUp, Linear, Google Tasks and Microsoft To Do. In addition, an AI Planner suggests where your tasks could fit in your day, and scheduling links let others book time with you.

Compared with Akiflow below, Morgen is calendar-first: you start from your schedule and fill the gaps with tasks. That makes it the better fit if you mostly need a strong calendar with planning built in.

**Pricing:** [Morgen](https://www.morgen.so/pricing)'s Pro plan costs $15 per month, billed annually. The Team plan costs $10 per seat per month, billed annually. Morgen's Team plan has a minimum number of seats, so check Morgen's pricing page for details.

### 9. [Akiflow](https://akiflow.com/)

![Akiflow task inbox next to a week calendar with tasks scheduled as time blocks](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-akiflow.png)

*Image:* [*Akiflow*](https://akiflow.com/)

**Best for:** People whose tasks are scattered across email, chat and project tools, and who want them in one plan.

Akiflow starts from the other end. It's a task inbox first: it collects to-dos from the apps you use every day, such as email, Slack, Notion and Todoist, so nothing slips through the cracks. You then drag those tasks onto your calendar as time blocks, much as you would in Morgen.

Akiflow has a desktop app for Windows and Mac, and it syncs with Google, Outlook and iCloud calendars. It's also designed for keyboard users, with a command bar for capturing a task from anywhere on your PC. On top of that, daily planning and shutdown rituals help you review what you got done and move the rest to tomorrow, which suits [batching](https://timingapp.com/blog/task-batching/) similar work together.

If your problem is too many inboxes rather than too few calendar features, Akiflow is the better choice. If you mainly want a strong calendar, Morgen is.

**Pricing:** [Akiflow](https://akiflow.com/pricing) Pro costs $19 per month, billed annually. Prices shown are Akiflow's US prices in USD. Akiflow's pricing varies by country, so you may see different amounts on its pricing page.

### 10. [Mozilla Thunderbird](https://www.thunderbird.net/en-US/)

![Thunderbird’s calendar tab in month view, with the mini calendar, calendar list and task pane](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-thunderbird.png)

*Image:* [*Thunderbird*](https://www.thunderbird.net/en-US/)

**Best for:** People who want a free, private calendar that keeps their data on their own PC.

Thunderbird is a free, open-source email app from MZLA Technologies, a subsidiary of the non-profit Mozilla Foundation, and it has a full calendar built in. You can keep calendars stored only on your PC, connect Google calendars, or sync with any CalDAV server, such as Nextcloud or Fastmail. Tasks live in the same app, and because it's open source and doesn't depend on ads, it's a good fit if privacy matters to you. [Thunderbird 159](https://www.thunderbird.net/en-US/thunderbird/releases/) came out on October 27, 2026.

There's one big catch for work users. Thunderbird connects to Microsoft Exchange and Microsoft 365 for email (Exchange since version 145, Microsoft 365 since version 154), but it can't sync their calendars or contacts yet. [Mozilla says](https://blog.thunderbird.net/2026/09/thunderbird-desktop-new-protocol-support-microsoft-graph-api/) Microsoft 365 calendar support is in development. Until then, if your organization allows it, you can publish your Outlook calendar as an ICS link and subscribe to it in Thunderbird, which gives you a read-only copy. If you need to edit your work calendar, choose one of the apps above instead.

Thunderbird's calendar also looks plainer than the dedicated apps on this list. It's practical rather than pretty.

**Pricing:** [Thunderbird](https://www.thunderbird.net/en-US/) is free. It's funded mainly by donations from its users.

## Other Apps Worth a Look

These two aren't calendar apps in their own right, so they're not in the numbered list. But each fixes a gap that a Windows calendar leaves: one turns your calendar into a daily plan, the other puts your agenda back on the taskbar.

### [Sunsama](https://www.sunsama.com/)

![Sunsama daily plan with tasks being dragged onto an Outlook calendar](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-sunsama.png)

*Image:* [*Sunsama*](https://www.sunsama.com/integrations/outlook-calendar)

**Best for:** A calm daily planning routine on top of the calendar you already use.

Sunsama is a daily planner that sits on top of your Google or Outlook calendar. Each morning, it walks you through choosing what to work on, estimating how long each task will take and placing it on your calendar, and it warns you when you've planned more than fits in the day. It has apps for Windows, Mac and Linux, plus iPhone and Android.

**Pricing:** [Sunsama](https://www.sunsama.com/pricing)'s Pro plan costs $17 per month, billed annually. An Enterprise plan with custom pricing is also available.

### [Calendar Flyout](https://apps.microsoft.com/detail/9P2B3PLJXH3V?hl=en-US&gl=US)

![Calendar Flyout showing today's agenda above the Windows 11 taskbar](https://timingapp.com/blog/media/2026/11/best-calendar-apps-windows-calendar-flyout.jpg)

*Image:* [*Calendar Flyout*](https://apps.microsoft.com/detail/9P2B3PLJXH3V?hl=en-US&gl=US)

**Best for:** Getting your agenda back on the Windows 11 taskbar.

Calendar Flyout is a small Windows 11 app that brings back what Windows 10 had: click it on the taskbar and you see a month calendar with your upcoming events underneath. It works with personal and work Microsoft accounts and with Google accounts. You can create, change and delete events from the flyout and join Teams or Google Meet calls with one click. It's a companion to your main calendar app, not a replacement. If you're looking for a calendar widget for Windows 11, this is the closest thing to it.

**Pricing:** [Calendar Flyout](https://apps.microsoft.com/detail/9P2B3PLJXH3V?hl=en-US&gl=US) costs $3.99 in the Microsoft Store, where it's rated 4.0 out of 5. Prices shown are Microsoft Store US prices in USD. Microsoft Store prices vary by country, so you may see different amounts in the Store.

## How to Choose the Best Calendar App for Windows

There's no single best calendar app for every Windows PC. The right one depends mostly on which accounts you use and how you like to plan:

- **Your work runs on Microsoft 365:** Start with Outlook. It's free, comes installed on newer Windows 11 PCs, and handles shared work calendars and Teams meetings better than anything else here. If you'd like a different app on top, Fantastical and eM Client both work well with Microsoft 365 accounts.
- **You live in Gmail:** Google Calendar in the browser is the obvious choice. For a desktop app with offline access, add your Google account to One Calendar, Wino or Fantastical.
- **You have an iPhone and a Windows PC:** Add your iCloud account to Fantastical, One Calendar or eM Client to see your Apple calendar on Windows, or open it at iCloud.com in your browser.
- **You want something free and native:** One Calendar for the widest account support, or Wino if you miss the old Mail and Calendar app.
- **You plan your day in time blocks:** Morgen if you want calendar-first planning, Akiflow if your tasks come from lots of different apps.
- **You care most about privacy:** Thunderbird with local or CalDAV calendars, as long as you don't need a Microsoft 365 work calendar.

Whichever app you choose, the habits matter as much as the software. Give your most important work a fixed slot, protect a few hours for [deep work](https://timingapp.com/blog/deep-work-increase-your-productivity/), and review your week before it starts. Our [time management tips](https://timingapp.com/blog/time-management-tips/) are a good place to begin.

## Frequently Asked Questions: Best Calendar App for Windows

### Does Windows have its own calendar app?

Not as a separate app anymore. Microsoft ended support for the Windows Mail and Calendar app on December 31, 2024, and replaced it with the new Outlook for Windows, which combines email and calendar. The new Outlook is free to use with ads, or without ads if you have a Microsoft 365 subscription.

### What is the best free calendar app for Windows?

For most people, it's the new Outlook if you use Microsoft accounts, or Google Calendar in the browser if you use Gmail. If you'd rather have a free native app that isn't tied to one company, One Calendar connects to almost any calendar account and works offline, and Wino Mail & Calendar is the closest thing to the old Windows Mail and Calendar app.

### Is there a Google Calendar app for Windows?

No. Google doesn't make a Google Calendar desktop app for Windows. You can use it in a browser and install the site as an app from Chrome or Edge, which gives it its own window. To see your Google calendar in a desktop app, add your Google account to the new Outlook or to a third-party app such as One Calendar, Wino or Fantastical.

### Can I use Apple Calendar on Windows?

There's no Apple Calendar app for Windows. You can open your calendar at iCloud.com in any browser, or add your iCloud account to a Windows app that supports it, such as Fantastical, One Calendar or eM Client. Your events then stay in sync with your iPhone.

### Which is better, Outlook or Google Calendar?

It depends on where the rest of your work happens. Outlook is the better choice on Windows if you use Microsoft 365, Teams and shared company calendars, and it runs as a desktop app. Google Calendar is better if you use Gmail and Google Meet, and it works the same in any browser, but on Windows it has no desktop app.

### How do I see my calendar on the Windows 11 taskbar?

The Windows 11 calendar that opens when you click the clock doesn't show your events. Microsoft announced an agenda view for the taskbar in November 2025 but delayed it in March 2026. Until it arrives, a small app such as Calendar Flyout adds an agenda to the taskbar, and Fantastical opens a mini window from the system tray.
