KOrganizer as a Linux alternative to Windows Calendar
Updated
Our verdict
KOrganizer is a capable replacement for Windows Calendar if you're on a KDE desktop and want deeper calendar and task integration. It supports Google Calendar, Microsoft Exchange (via CalDAV or GroupDAV), and iCloud through CalDAV, so core syncing needs are met. The monthly view, event creation, and reminders work well. However, it’s heavier than Windows Calendar and less intuitive for casual users. Best suited for Linux users who want advanced features and are already in the KDE ecosystem.

What works the same
- Supports Google Calendar via CalDAV
- Syncs with Microsoft Exchange and Outlook.com (using CalDAV or KDE's Akonadi)
- Provides a monthly calendar view
- Allows event creation with customizable reminders
- Supports recurring events
What is different
- KOrganizer is more feature-rich and heavier; not 'lightweight' like Windows Calendar
- No direct native integration with email unless using Kontact
- iCloud support requires manual CalDAV setup, not automatic
- Task management is built-in, which Windows Calendar lacks
- Keyboard navigation is strong, but UI is denser and less beginner-friendly
Opening your Windows Calendar files
Windows Calendar doesn't export standard calendar files directly, but if events are exported via Outlook or another Microsoft tool as .ics (iCalendar) files, KOrganizer can open them without issue. KOrganizer supports full iCalendar format import and export, so any standard .ics file from Google, Outlook, or iCloud can be used. Direct file migration from Windows Calendar isn't straightforward unless synced through a common account.
Switching from Windows Calendar to KOrganizer, step by step
- Enable CalDAV sync for your Google, Exchange, or iCloud account
- In KOrganizer, go to Settings > Configure Calendars and add the account via CalDAV
- Enter server details and credentials for each calendar
- Verify calendars appear in the monthly view
- Set up reminders and test event creation
- Use KDE Connect on mobile to sync with Android if needed
