Maira Mehtab Sep 21, 2026 869 views

Question details

The user needs to change the date format in the Microsoft To Do web app from the US format (MM/dd/yyyy) to a regional format like dd/MM/yyyy.

Product: Microsoft To Do
Device & OS: not provided
Scenario: Viewing and managing task due dates in the Microsoft To Do web application.
Observed behavior: Due dates display in MM/dd/yyyy format even when Microsoft 365 and browser regional settings are set to English (Australia). Other apps like Outlook show the correct format, but To Do lacks an independent date-format toggle.

Before you start

Ensure you have access to your global Microsoft 365 account settings, as the date format in Microsoft To Do cannot be adjusted within the app itself and requires an account-level language change.

Solution 1Recommended

Change Microsoft 365 Language Settings to English (United Kingdom)

Switching your global Microsoft 365 language setting to English (United Kingdom) forces the associated web apps, including Microsoft To Do, to adopt the standard dd/MM/yyyy date format.

Microsoft To Do relies on your overarching Microsoft 365 profile settings for its date formatting. Since some regional English settings (like Australia) may not fully enforce the dd/MM/yyyy format within the To Do web app specifically, switching to UK English acts as a reliable workaround.

Access Microsoft 365 Settings

Log into your Microsoft 365 account on the web. Click the gear icon located in the top-right corner to open the Settings pane.

Navigate to Language and Time

In the Settings menu, go to 'General', and then select 'Language and time'.

Select English (United Kingdom)

Under the language configuration options, change your display language from your current setting to 'English (United Kingdom)'. Save your changes if prompted.

Refresh Microsoft To Do

Open or refresh the Microsoft To Do web app. Your task due dates will now correctly display in the dd/MM/yyyy format.

Global Setting Updated: This change will also apply the UK English format to other connected Microsoft 365 web applications, ensuring a consistent date display across your workflow.

Frequently Asked Questions

Why does Microsoft To Do ignore my browser's regional settings?

Microsoft To Do web app relies entirely on your global Microsoft account profile settings rather than your local browser or operating system configurations. If your chosen region is not perfectly mapped to the dd/MM/yyyy format within To Do's backend, it defaults to the US format.

Will changing my language to UK English affect other Microsoft apps?

Yes, changing the language in the global Settings > General > Language and time menu will apply to all interconnected web-based Microsoft 365 applications, such as Outlook and Calendar. They will adopt standard UK English spellings and the dd/MM/yyyy date format.

Can I change the date format only within Microsoft To Do?

No, Microsoft To Do currently does not offer a standalone setting to customize the date and time format exclusively for the app. You must change the language settings at the Microsoft 365 account level.
