Distinct list of months and years

Been racking my brains on this, but not come up with a solution yet.

I've got a collection of dates in a range and I'm trying to create a new collection from that, consisting of two columns - the distinct months and the years of those months.

e.g. my date range is from 2020-11-14 through to 2021-02-11 and I want the end result to be:

November	2020
December	2020
January	2021
February	2021

Getting the distinct months into a collection is easy enough, but it's adding the corresponding year that I'm stuck on. Any help would be appreciated.

Hi @JamesSnaps :

I've made a test for your reference:

1\I assume there is a collection named DateRange

ClearCollect( DateRange, ForAll( Sequence(DateDiff(Date(2020,11,14),Date(2021,2,11),Days),0,1), {TheDate:DateAdd(Date(2020,11,14),Value,Days)} ) )

2\Add a date table control and set it's Items property to:

ForAll( Distinct( ForAll( DateRange, { TheValue: Text( TheDate, "[$-en]mmmm" ) & ";;" & Year(TheDate) } ), TheValue ), { TheMonth: First( Split( Result, ";;" ) ).Result, TheYear: Last( Split( Result, ";;" ) ).Result } )

Best Regards,

Bof
