Microsoft Lists Calendar View Starts with wrong day of the week

[BMorgy99]

Hi,

Does anyone know why my Calendar view (both in Teams and Sharepoint) starts on a Wednesday instead of either Sunday or Monday as specified in settings?  See below.  I've checked regional settings at the site level, on my computer, in outlook, and every other place I can check.  Why Wednesday?

That's very strange and there is nothing you would need to do at least for the the Teams Calendar App. in my case, the starting day is Monday
