How to Change the First Day of the Week in Project for the Web
Question details
The user wants to configure the calendar view to start on a different day (such as Monday instead of Sunday) in Project for the Web.
- Product
- Project for the Web
- Device & OS
- not provided
- Scenario
- Customizing the project calendar layout to align with local business weeks and scheduling preferences.
- Observed behavior
- Project for the Web defaults to Sunday as the first day of the week and currently lacks a user-facing setting to change this configuration.
Verify that you are using the browser-based Project for the Web rather than the Project Online Desktop Client, as the desktop version possesses different calendar customization capabilities.
Acknowledge the Limitation and Submit Feedback
Currently, modifying the week's starting day is not supported in the web version. Users must submit a feature request to Microsoft to encourage future development.
The browser-based Project for the Web calendar has a known product limitation where the first day of the week is hardcoded to Sunday. Unlike other Microsoft 365 apps, there is no regional or tenant-level setting that will adjust this web experience.
The official workaround recommended by Microsoft is to utilize the Feedback portal to vote for this specific feature implementation.
Check your browser to ensure you are logged into Project for the Web. Recognize that the settings gear icon does not currently house a calendar or regional configuration tab.
Open a new browser tab and navigate to the official Microsoft Project Feedback forum (feedbackportal.microsoft.com).
Type 'change first day of the week' in the search bar. If you find an existing thread regarding Project for the Web, click the 'Vote' button.
If no thread perfectly matches your issue, click 'Send feedback', describe your need to change the calendar start day to Monday, and submit the request.

Frequently Asked Questions
Can I change the first day of the week in the Microsoft Project desktop client?
Yes. In the Microsoft Project desktop application, you can adjust this by navigating to File > Options > Schedule, and then changing the 'Week starts on' setting to your preferred day.
Will changing my Microsoft 365 regional settings affect Project for the Web?
No. While regional settings dictate the calendar layouts in Outlook and SharePoint, Project for the Web currently ignores these settings and defaults to a Sunday start globally.
Is there a browser extension to fix the calendar view in Project for the Web?
No reliable browser extensions currently exist to restructure the grid view in Project for the Web, as the calendar layout is rendered directly by Microsoft's backend servers.
Does WPS Office include project management features?
While WPS Office does not include a dedicated standalone project management app, WPS Spreadsheet offers extensive formulas and templates designed specifically for Gantt charts, timelines, and agile project tracking.
