Hi Marvin,

Thanks for the quick reply!

There were hidden sheets, but it was just the two years previous, still no data dump. I'm looking at the VBA properties list for the worksheet, but I can't find anything regarding a code, what am I looking for?

I'm not sure if this is helpful, but this is the formula on each day of the calendar:

=IF(AND(YEAR(FebSun1+1)=TheYear,MONTH(FebSun1+1)=2),FebSun1+1, "")

Thanks!
