ISO 8601 week of year

Hi, 

 

I'm having trouble create a date based on the standard ISO "week of year" format (YYYY-WXX-DD). I've created a simple flow that just takes initialises a variable with

formatDateTime('1979-W01-1'), which produces an error
 '1979-W01-01' was not valid. The datetime string must match ISO 8601 format.'.
 
Hopefully i'm doing something wrong, it'd be quite annoying if flow only worked on a subset of ISO 8601 formats!

Unfortunately, you aren't doing anything wrong.  formatDateTime uses the standard Microsoft date formatting strings. So there is no support for a week number.  This is a common issue across the Microsoft platforms including Power BI
