Week Start calculation

[mcnater]

I'd love to be able to group my dates into Week Start buckets. In Qlikview there is a WeekStart() function where you provider a date and it groups dates into weeks, depending on the date and offset you provider so you can easily do this. I'm not finding something similar in PBI yet. Does anyone know how to do this?  Basically looking to add 1 new column to my calendar table. I already have the weeks numbered, but I need the "display" value now so we'd see thing slike 6/2/2018, 6/9/2018, 6/16/2018 and so on as the labels.
