What is Windows Calendar?
Windows Calendar is used primarily for managing personal and work events, appointments, and reminders. It integrates directly with Microsoft accounts and Exchange, making it popular among Windows users in both home and office environments. Its clean monthly and daily views suit casual users and professionals who rely on cloud-synced calendars.
The app is free and comes preinstalled with Windows 10 and 11. There is no separate purchase or subscription required, and it does not display ads. Licensing is tied to the Windows operating system, and all features are available by default without in-app purchases.
People seek Linux alternatives because they want similar ease of syncing with online calendars (especially Microsoft and Google) and a simple, integrated experience. Linux desktops don’t include a default calendar app with the same level of account integration, so users look for reliable replacements that support event management and cloud sync.

- Syncs with Google Calendar
- Syncs with Microsoft Exchange or Outlook.com
- Supports iCloud Calendar
- Monthly calendar view
- Event creation and reminders
- Lightweight and easy to use

Can you run Windows Calendar on Linux?
There is no native Linux version of Windows Calendar. It does not run reliably under Wine, Proton, or Bottles due to deep Windows integration. However, the functionality is widely available through Linux-native apps that support CalDAV and Exchange Web Services, which can replicate the syncing behavior with online accounts.
Which alternative should you choose?
GNOME Calendar is best for users wanting a simple, clean interface on GNOME desktops. Thunderbird works well if you also manage email and want tight calendar integration. KOrganizer suits KDE users needing advanced features like task management. Evolution is ideal for enterprise environments with Exchange or heavy groupware use.
Moving your Windows Calendar files and habits
Exporting data from Windows Calendar requires using the associated account (Microsoft, Google, etc.) since the app itself doesn’t export files directly. Events synced to Google, Outlook.com, or iCloud can be accessed on Linux by adding the same account to any of the alternative apps. CalDAV and Exchange support ensure compatibility across platforms.
