SharePoint Calendar Time Zone Conversion Issues and Workarounds

Question details

Users in different regions see varying date and time values in SharePoint Online calendars due to automatic time-zone conversions based on site or regional settings.

Product: SharePoint Online
Device & OS: not provided
Scenario: Managing calendar events, list items, and dates for a distributed team across multiple time zones within a SharePoint site.
Observed behavior: SharePoint automatically converts time values based on the site's regional configuration, preventing users from entering or viewing dates independently in their local time zone.

Before you start

Verify the current regional settings of your SharePoint site by navigating to Site Settings and clicking on Regional Settings to understand the baseline time zone being applied.

Solution 1Recommended

Store Time Zones in a Separate Text Column

Bypass the automatic conversion by storing the actual time zone or local time as a standard text string that SharePoint cannot alter.

Since SharePoint forces date and time fields into the site's regional time zone, the simplest workaround is to avoid using the default Date/Time column format for specific local hours.

Create a new column

Navigate to your SharePoint list or calendar, click 'Add column', and select 'Single line of text'.

Name the column appropriately

Name the new column 'Local Time' or 'Time Zone' so users can manually input their specific regional time.

Enter the unformatted time

Instruct users to type their local time and time zone abbreviation (e.g., '10:00 AM EST') directly into this text field.

Text fields remain static: Unlike Date/Time columns, text columns are not subject to SharePoint's automatic time zone recalculation and will display exactly as typed for all users.

Solution 2

Apply Custom Logic using Power Apps and Power Automate

Build a customized entry form that calculates and normalizes time zones dynamically based on user profiles.

Frequently Asked Questions

Why does SharePoint change the time I enter in a list or calendar?

SharePoint Online standardizes date and time inputs by converting them according to the regional time-zone configuration set at the site level. This ensures a single timeline but can result in different display times for users viewing the site from other time zones.

Can I set SharePoint to allow each user to enter dates in their own local time?

No, currently there is no standard setting in SharePoint that allows users to independently enter and freeze dates in their local time zone without conversion. It is a known design limitation by Microsoft.

How do I check my site's regional time zone settings?

You can check this by navigating to your SharePoint site, clicking the gear icon for Settings, selecting 'Site Information', and then 'View all site settings'. From there, click on 'Regional settings' to view the default time zone.
