Hi Everyone,
Its my first post in the forum so apologies if the post is posted incorrectly.
I want to convert weekly dates to fortnightly dates. While this sounds simple - I cant seem to get it working. I know there was a similar post: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Grouping-dates-into-fortnights/m-p/949837 but this didnt quite work for me as the numbers didn't while line up.
This is the data I have which goes up to 2023 (see below). I essentially want the 'Fortnight' column to show 06/01/21 for the first period. Then from 7/01/21 - 20/01/21 to show as 20/01/21 and 03/02/21 for the next 2 week period and so on.
I intially tried
Any help would be greatly appreciated!
Kind regards,
Mike

@Michaelc1993 , Try a new column like
New column
VAR __BaseDate = DATE(2021,1,6)
return
quotient(datediff(__BaseDate,[Date],day),14) +1
if we need a yearly reset, we have start using week year start date, in place of DATE(2021,1,6)
Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week Start Year = minx(filter('Date',[Year] =earlier([Year])),[Week Start date])
