Need a sameperiodlastyear type formula to dynamically compare current and last year.

Hey there!


I'm in need of a dynamic same period last year comparison between 2022 and 2021. Currently my SAMEPERIODLASTYEAR formula returns the below results giving me a full last year comparison against the current year.

SUM LY Sameperiod = CALCULATE(sum('My Dataset'[Amount]), SAMEPERIODLASTYEAR('Date Table'[Date]))


I would like a formula that returns last year data for the same period as I have current year data ie. Jan 1 - Nov 23 for both 2022 and 2021. The report will update every day adding another day and it should be reflected in the report. I do not want to use manual filters like slicers.


Thank you very much!
