I need a formula or process that allows you to determine the number of
specific days (Mondays, Tuesdays, etc) between two dates.

Here is a formula from Daniel M

=SUM(--(WEEKDAY(A2-1+ROW(INDIRECT("1:"&TRUNC(B2-A2)+1)))=C2))

A2, B2 are the 2 dates, C2 is the day of the week (1=Sun, 2=Mon, etc.)

It is an array formula, so commit with Ctrl-Shift-Enter.

Neat formula. But if A2 and B2 are "dates", why the TRUNC function? Or did it
come from a construct where times were included?

Hi Bob,

Brute force!? : That must be from my earlier days ;-))

The number of DOW (1= Sunday, 2 = Monday, ..., 7 = Saturday) between a start
date (A1) and an end date (A2) is :

=INT((A2-WEEKDAY(A2+1-DOW)-A1+8)/7)

Regards,

Daniel M.

Hi Daniel,

It is the one I have in my library, but checking Google, I see that you have
'moved on' :-)

do have a twist on the earlier questions and wondered if anyone knows how to
do it. Im trying to do the following:

Within a date range (say 1/5/05 to 3/25/05) I would like to identify each
month and further find the number of Mondays, Tuesdays, and etc, within each
month.

Any thoughts? Thanks for the help,

Assuming the dates are in A1 and B1, this will return the number of Mondays
in January

=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(A1&":"&B1)),2)=1),--(MONTH(ROW(INDIRECT(
A1&":"&B1)))=1))

The first = 1 refers to the weekday (1 through 7 for Mon through Sun), the
second refers to the month number.

Use DAYS360 or NETWORKDAYS (use this one if you only want to calculate
business days).
