- Product
- Microsoft Planner
- Device & OS
- not provided
- Scenario
- Viewing task due dates and timelines in Microsoft Planner through a web browser or the Microsoft Teams desktop application.
- Observed behavior
- Planner continues to display dates in the US format (MM/DD/YYYY) even when the user's operating system regional language settings are set to UK or Australian English.
Before making changes, verify whether you primarily access Microsoft Planner through a web browser or the Microsoft Teams desktop app, as the date format settings must be adjusted within the specific host application you are using.
Change Web Browser Language Settings
Adjust your web browser's language preferences to force Planner's web interface to display dates in your preferred regional format.
Microsoft Planner's web version relies on your browser's language settings rather than your computer's system settings. By prioritizing a regional English variant, Planner will automatically adjust its date display.
Open your web browser (such as Microsoft Edge or Google Chrome) and navigate to the main Settings menu.
Search for 'Language' in the settings search bar or navigate directly to the Languages section in the sidebar.
Click 'Add languages' and search for 'English (United Kingdom)' or 'English (Australia)', then add it to your list.
Move the newly added regional English to the very top of your language list so the browser uses it as the primary display language.
Close all active browser windows and reopen them. Navigate to Microsoft Planner to verify the dates are now in the DD/MM/YYYY format.

Change Microsoft Teams Language Settings
If you use the Planner app embedded within Microsoft Teams, you must change the language settings directly inside the Teams desktop application.

Frequently Asked Questions
Why does Microsoft Planner ignore my Windows system regional settings?
Microsoft Planner currently relies on the language settings of the host application (like your web browser or Microsoft Teams) rather than the operating system's global regional settings. This is why you must change the language within the browser or Teams itself.
Can I change the date format in the Planner mobile app?
Yes, the Planner mobile app typically inherits the language and region settings of your mobile device. Ensure your phone's primary language is set to UK or Australian English in the iOS or Android system settings to update the Planner app's date format.
Will changing the Teams language affect other users in my organization?
No, changing the language and regional settings in your Microsoft Teams desktop app or web browser only affects your personal view. It will not change how dates or language text appear for other team members.
Is there a built-in toggle inside Planner specifically for date formats?
Currently, there is no standalone setting within Planner's own interface to switch date formats. You must adjust the browser or Microsoft Teams language preferences to force the date display to change.
