Hello,
I want to calculate number of days belonging to each month within a given week, e.g. if i have
week no 1 29Dec08 until 4Jan09
week no 2 5Jan09 until 11Jan09
week no 3 12Jan09 until 18Jan09
week no 4 19Jan09 until 25Jan09
week no 5 26Jan09 until 1Feb09
I would like to calculate the split of days belonging to December, January,February etc; in this case it would be
week no 1 - 4 in Dec and 3 in Jan
week no 2 - 7 in Jan
week no 3 - 7 in Jan
week no 4 - 7 in Jan
week no 5 - 6 in Jan & 1 in Feb
I've tried to use eomonth formula but even with Analysis Tool Pack it doesn't work.
thank you.

The specifics depend on you have your data set up, and how you want to display
the results. But, in general,

with a Starting Date in A2
Ending Date in B2

The number of days in that range that are in the same month as the starting
date: =SUMPRODUCT(--(MONTH(ROW(INDIRECT(A2&":"&B2)))=MONTH(A2)))

The number of days in that range that are in the same month as the ending date:
=SUMPRODUCT(--(MONTH(ROW(INDIRECT(A2&":"&B2)))=MONTH(B2)))
--ron

If there is to be a split across 2 months, then the day of the month in the
ending date will be 1, 2, 3, 4, 5 or 6.

Assuming your first date is in cell A2 and the second date is in B2, this
formula will give you the number of days in the 1st month
=IF(DAY(B2)<7,7-DAY(B2),7)
and then (if that formula is in C2) you can use this to get the number of
days in the second month:
=7-C2
