Date Grouping

[Anonymous]

When grouping my date for 7 days, it always refers to Sunday as the first day of the week. Is there a way to control the start day of the week when grouping by 7 days?

@Anonymous  How are you doing the Date Grouping? Here's my blog on Date tables: https://excelwithallison.blogspot.com/2020/04/dimdate-what-why-and-how.html

You can see in the M code part I have commented in the code how to change the start of week day. 

Hope that helps!
