Transform date to weeknumer in year gives the wrong result

[Anders_No]

I have a date - and by right-clicking on the header -> Transform -> Week -> Week of year, I get the weeknumber.

However, the weeknumber provided does not fit with the calendar - as we should be in week 1now.

Power BI starts with week one 1. January which is a Friday and not a Sunday, which I read is the start day in Power BI (though I think it should be Monday).

Anyone having the same isue/know whar to to?

Hi @v-lili6-msft ,

I was not aware that weeknumbers had different definitions until I saw mikejarods post - so yes, that was my issue.

Thank you so much for your time - I will try a work around!

Regards

Anders
