How to handle February end date when forecasting?

[nleuck_101]

Hello All,

I'm trying to create some forecast but I notice that have an issue with February and could use some help. I have a date field, a column with data at the end of the month and a forecast column. I have the visual filtered to only show the end of month. My formula for the forecast is:

Forecast = CALCULATE([Measure], SAMEPERIODLASTYEAR(DateTable[date_field]))

As you can see there 02/28/21 does not have data for the forecast because the previous February end date is 02/29/2020. Moving forward that could create an issue when we have the next leap year. Is there a way to solve this?

Instead of using SAMERPERIODLASTYEAR, I used PARALLELPERIOD and that seemed to work.
