Hi Chaim

Sergey's formula is correct, but IMO it is actually two functions in one.

This part means get the first day of the month: ldDate-DAY(ldDAte)+1. That of itself should be a UDF. FirstDayOfMonth(m.ldDate)

Then there is the part that gets the last day of the month.

GOMONTH(FirstDayOfMonth(m.ldDate),1) -1

So what Sergey said is:

?Day(LastDayOfMonth(m.ldDate))
