How to Fix the Wrong Time in a SharePoint Group Calendar
Question details
The user needs to correct the displayed time for events in a modern SharePoint group calendar that does not match the Outlook meeting time.

- Product
- SharePoint
- Device & OS
- not provided
- Scenario
- Viewing group events synced between Outlook and a modern SharePoint calendar.
- Observed behavior
- The SharePoint group calendar displays events several hours earlier or later than the correct Outlook meeting time due to mismatched regional settings.
Ensure you have Site Administrator permissions in SharePoint to modify site regional settings, and confirm the correct meeting time in your local Outlook application before making changes.
Update SharePoint Site Regional Time Zone Settings
Correcting the site's regional time zone will align the SharePoint calendar times with your local Outlook meetings.
SharePoint group calendars rely on the underlying site's regional settings to display date and time information. If the site is configured for a different time zone than your Outlook application, events will appear shifted by several hours.
Open your SharePoint site, click on the Settings gear icon in the top right corner, select 'Site contents', and then click on 'Site settings'.
Under the 'Site Administration' section, click on 'Regional settings' to view the current site configuration.
Verify the current site time zone. Select the correct time zone from the dropdown menu to match your local region or Outlook settings, then click 'OK' to save.
Check whether the incorrect time appears in SharePoint, Outlook, or both. Allow several hours for the regional update to fully sync across the group calendar.

Frequently Asked Questions
Why does my SharePoint calendar show events 8 hours early?
This discrepancy occurs when the SharePoint site's regional time zone is set to a default (such as Pacific Time) while your Outlook application is operating in a different time zone (such as GMT). Updating the SharePoint regional settings to match your local time zone will fix this.
Do I need admin rights to change the time zone in SharePoint?
Yes, changing the regional settings for a SharePoint site requires Site Owner or Site Administrator permissions. If you do not see the 'Site Administration' or 'Regional settings' options, you will need to contact your IT department.
Will changing the SharePoint time zone affect other users?
Yes, modifying the site's regional settings changes the default time zone for all users viewing that specific SharePoint site. However, if individual users have configured personal regional settings in their SharePoint profiles, their personal settings will override the site defaults.
Why is the calendar time still wrong after I changed the settings?
SharePoint background synchronization can take time. It is highly recommended to wait a few hours after making the change, then refresh the page or clear your browser cache to see the corrected event times.
