6 Week Offset

[William_Walk]

Hi

Currently looking for a solution for my Calendar Table. I have dates ranging from years 2018 - 2035. I need a collumn that takes 6 weeks for an offset. I want it so I can measure yearly data but within 6 week periods. Any chance anyone can think of a solution. Cheers 🙂

Thank you for the help, is there anyway of getting this to reset for every january so that when we go from december 2018 to january the 1st the 6 week offset resets back to 1.

Thanks

@William_Walk , Assume you want 6 week offset staring from 2018

You can have have a new column like

New column=

var _min = min(Date[Date])

var _diff = datediff(_min, [Date], day)

return 

quotient(_diff, 42) +1

If need you can move the first date sunday or monday using the week start logic
