Many Windows 11 users rely on the Calendar app to manage their appointments and meetings efficiently. Sometimes, the appointment duration settings may not work as expected, causing confusion and scheduling errors. Fixing this issue ensures your calendar entries reflect the correct time slots.

This guide will walk you through simple steps to resolve appointment duration problems in the Windows 11 Calendar app. Each step is explained clearly for users at all levels.

By following these instructions, you can get your calendar back to working smoothly without missing important events. Let’s get started with the basic checks before moving to advanced solutions.

Remember, small settings or system glitches often cause these issues, so patience and careful attention are important.

Quick Note: Prerequisites and Basic Checks

• Ensure Windows 11 is updated: Running the latest system updates can fix known bugs in built-in apps like Calendar.
• Verify Calendar app version: Make sure your Calendar app is up to date via the Microsoft Store.
• Check your default calendar account: If you use multiple accounts, confirm which calendar is active, as different accounts may have different settings.
• Restart your device: Sometimes, a simple reboot resolves temporary glitches affecting app behavior.

Step 1: Check Appointment Duration Settings in the Calendar App

First, confirm that the appointment duration is set correctly inside the app itself. Here’s how:

1. Open the Calendar app from the Start menu or taskbar.
2. Click on the New Event button to create a test appointment.
3. Look at the Start time and End time fields.
4. Manually set the correct duration by adjusting the end time accordingly.
5. Save the event and check if the duration is displayed correctly on your calendar view.

Why this matters: Sometimes, the appointment duration isn’t automatically calculated, so manually setting it ensures the app registers the time slot correctly.

Step 2: Adjust Default Appointment Duration in Calendar Settings

If you want to set a default duration for all new appointments, follow these steps:

1. Open the Calendar app.
2. Click on the Settings icon (gear symbol) located at the bottom left corner.
3. Select Calendar Settings or Event Settings (depending on the version).
4. Find the option for Default appointment duration.
5. Choose your preferred time (e.g., 30 minutes, 1 hour).
6. Close the settings and create a new appointment to test if the default duration is applied.

Why this helps: Setting a default duration saves time when creating appointments and ensures consistency across your calendar.

Step 3: Sync Issues and Account Settings

If your calendar is linked to online accounts like Outlook, Google, or Exchange, syncing problems can affect appointment durations.

1. Open the Settings app on Windows (press Win + I).
2. Go to Accounts → Email & accounts.
3. Select the account connected to your Calendar app.
4. Click Manage or Sync and ensure syncing is working properly.
5. If syncing fails, remove and re-add the account to refresh calendar data.

Why this is important: Calendar appointment durations may not update or display correctly if account data is out of sync with the app.

Step 4: Reset or Repair the Calendar App

If the above steps don’t fix the problem, resetting the app can clear corrupted data or settings.

1. Open Settings and navigate to Apps → Installed apps.
2. Find the Calendar and Mail app in the list.
3. Click the three dots menu next to it and select Advanced options.
4. Scroll down and click Repair. This attempts to fix the app without deleting your data.
5. If repair doesn’t help, click Reset. Note that this will erase all app data and settings.
6. After resetting, reopen the Calendar app and test the appointment duration again.

Why reset matters: Apps occasionally develop bugs or corrupt files that impact their functions. Resetting restores the app to its default state.

Alternative Method: Use Web Versions or Third-Party Apps

If you continue facing issues, consider accessing your calendar via the web version:

• Outlook Calendar: Visit Outlook Calendar online for full control over settings.
• Google Calendar: Use the web interface at Google Calendar if your account is synced.
• Third-party apps: Some users prefer apps like Thunderbird or Microsoft Outlook desktop client for more robust calendar management.

These alternatives can bypass app-specific bugs and offer more customization options.

Frequently Asked Questions (FAQs)

Why does my Calendar app ignore the appointment duration I set?

This often happens due to sync issues, app bugs, or conflicting default settings. Checking sync status and adjusting default durations usually fixes the issue.

Can I change the appointment duration for existing events?

Yes, you can open any event and manually adjust the end time to change the duration. However, default durations only apply to new events.

Does resetting the Calendar app delete my calendar data?

Resetting clears local app data but not the data stored in your online calendar account (e.g., Outlook or Google). Your events remain safe online.

What if my Calendar app does not open or crashes?

Try repairing or resetting the app as described above. If problems persist, consider reinstalling or using the web version temporarily.

Is there a way to set different default durations for different calendars?

Currently, the Windows 11 Calendar app applies one default duration across all calendars. For more granular control, use dedicated calendar software or web interfaces.

When Nothing Works

If none of the above solutions restore your appointment duration settings, consider these final options:

• Run Windows Troubleshooter: Go to Settings → System → Troubleshoot → Other troubleshooters → Windows Store Apps.
• Create a new Windows user profile: Sometimes, user profile corruption causes app issues.
• Contact Microsoft Support: Visit the official Microsoft support page for direct help.
• Use Feedback Hub: Report the issue via the Feedback Hub app to alert Microsoft developers.

Conclusion

Fixing appointment duration settings in the Windows 11 Calendar app is usually straightforward. Start by verifying your settings and updating both Windows and the app. Sync issues and account problems are common culprits, so checking those is essential.

If simple fixes don’t help, repairing or resetting the app often resolves deeper problems. When needed, use web versions or third-party apps as effective alternatives.

By following this step-by-step guide, you can ensure your calendar appointments display the correct duration and help you manage your schedule without hassle.
