first day of week in calendar of Microsoft Teams

Occasional Contributor

I have set Saturday as the first day of the week and Microsoft Outlook shows the week days in the correct order. But calendar of Microsoft Teams shows Saturday as the last day of the week. How can I fix this problem?
I am the admin of my organization tenant but I did not see any settings for this matter in Teams Admin.

This is depending on the app language you set in the client! For example if you have English (UK) you will have mon-sun and if you set the app language to English (US) it will change to sun-mon

There’s currently no other way of doing this.
There is a uservoice for this so go in and vote/


Thanks for this information, I have now been able to set my work week to start on Monday. Kind of annoying that things like this are hidden in the language settings. And I don't know of anyone in Australia (where I live) that starts their work week on Sunday! I have changed my language settings in Teams to be English UK so that I can get the work week to start on the correct day. This should just be a separate setting, independent of language.

@GlenOFI I think it is not only annoying, but rediculous, to have calender settings hardcoded to language. I speak american engkish since i've studied and spent 3 years in teh states, but i live and work in europe. 


Right now, fior thsi group, my settings are american english, yet the autocorret doesnt work - for some reason the os overrueld tehs settings and try to correct "swedish".


I dont bother. What is tie point of selecting settings when they dont work...

Restart Outlook & Teams the new settings will take effect. This worked for me.
