Microsoft Booking - Calendar starts on Sunday instead of Monday

Hi,

Thank you for sharing your question. Hey, thanks for asking about the Microsoft Bookings calendar starting on Sunday. I get that it's confusing when your account and booking page are set to a European place where Monday is the normal first day of the week, but the booking page starts with Sunday. Sorry for the trouble this causes.

What you're seeing happens because Bookings gets some display settings from Outlook on the web and the booking page's regional settings. But it doesn't always change the first day of week for the public page based on where your account is located. Bookings uses your Outlook calendar settings for its internal calendar, but the booking page for customers uses its own Change language and time zone settings. This controls the language and time zone, but it doesn't have a first day of week option. So, even if you have a European place set, the public page might still show Sunday first.

Here's what you can do to fix it: First, check the staff admin's Outlook on the web calendar settings and set the work week to start on Monday. Bookings uses these Outlook settings for the signed-in user and shows them in the Bookings calendar. Then, go to Bookings and change the booking page's regional settings using Change language and time zone settings to make sure the language and time zone match your place. This controls how the public page shows the language and time zone. Doing these things will help, but the public page doesn't have a way to force Monday as the first day. That's why you might still see Sunday first.

I hope this helps.

Best Regards,

Noel

A Feedback thread on this issue exists here: https://feedbackportal.microsoft.com/feedback/idea/c99e046e-78f7-f011-92b8-7c1e529e52bb and I have added on to it.

Hello @HanakJ,  

Thank you for reaching out to the Q&A forum! 

After receiving your message, I researched this behavior further and also tested it in my own environment. Even when I change the region and time‑zone settings inside the Booking Page, the public booking page continues to display Sunday as the first day of the week. 

I also tried modifying the “First day of the week” setting in Outlook on the web to Monday.  

This setting is correctly reflected inside the internal Bookings calendar, but the public facing booking page still starts with Sunday regardless of the Outlook configuration. 

During my research, I checked Microsoft’s official documentation here: Customize and publish your booking page | Microsoft Learn. The screenshot included in that article also shows the calendar beginning with Sunday, which strongly suggests that this may be the expected behavior of the current product design. 

At this moment, there is no published Microsoft roadmap indicating that this will be changed in the future. I also reviewed this Microsoft Q&A discussion; other users have reported the same behavior: Start work week in Microsoft Bookings - Microsoft Q&A   

And as far as I can see, this does have some impact on the workflow of organizations in Europe, where Monday is the standard first day of the week. Because of that, I highly recommend submitting feedback through the Microsoft Feedback Portal.

This allows the development team to understand the needs of real users. Your feedback may help us revive or introduce features that make a real difference.         

If you've already submitted feedback, please share the link here, so not only me, but others can also vote it up. I truly appreciate you're understanding and patience as Microsoft continues to evolve the platform.           

Looking forward to you!
