calendar events keep showing one hour earlier than the time set

Hi @Geoffrey Owen,

Thank you for posting your question in the Microsoft Q&A forum.

Based on what you described (5 PM showing as 4 PM), it’s usually due to mismatched time zone or daylight-saving settings. Please try these steps:

Step 1: Check Windows time settings:

1. Open Settings > Time & Language > Date & Time.
2. Make sure:
   • Set time automatically = ON.
   • Set time zone automatically = ON.
     
3. Confirm the correct time zone is displayed.

If your organization manages these settings, you may need to contact your IT admin.

Step 2: Verify Outlook time zone:

1. In New Outlook for Windows, click the gear icon.
2. Go to Calendar > View.
3. Ensure the time zone matches your Windows setting.

Step 3: Remove extra time zones:

If you added multiple time zones in Outlook, temporarily remove them to test.

Step 4: Restart Outlook and your PC after making changes.

For references, you can see:

• Manage time zone settings in Outlook
• Daylight Saving Time in New Outlook Calendar
• Multiple time zones show an incorrect time difference when DST starts and ends
• Set time, date, and time zone settings in Windows
