I'm trying to calculate difference between dates, but with a twist- I need to
return the number of full months between beginning and end dates, then, in
the next cell over, the remaining days. Here's where I am so far
(M=BeginDate, N=EndDate) for Months:
=IF(OR(M13="",N13=""),"",IF((DAY(M13)=1),(YEAR(N13 )-YEAR(M13))*12+MONTH(N13)-MONTH(M13)+1,(YEAR(N13)-YEAR(M13))*12+MONTH(N13)-MONTH(M13)))

Days:
=IF(OR(M13="",DAY(M13)=1),"",IF(N13="","",DAY((EOM ONTH(M13,0))-DAY(M13)+1)))

This is returning properly only if EndDate is the last day of a month. I
need it to work regardless of when the month the EndDate falls. Any
suggestions? Any help is much appreciated!
