I am looking for a formula that will count the number of Sundays within a
date range. Example: I want to enter a start date in one cell, and today's
date in another,and need a formula that will count the number of Sundays
between the two.A1 3/01/2008
A2 3/31/2008
A3 5 (5 Sundays between the dates)

If the two dates are:

Sunday, March 23, 2008
Sunday, March 30, 2008

does that count as two Sundays, one Sunday, or no Sundays??

{=SUM(IF(WEEKDAY(A1-1+ROW(INDIRECT("1:"&TRUNC(A2-A1)+1)))=1,1,0))}

Do not type the outter brackets { } . This is an array formula committed by
Ctrl+Shift+Enter.

Hi,

Srat date in a1
End date in b1

=SUM(IF(WEEKDAY(A1-1+ROW(INDIRECT("1:"&TRUNC(B1-A1)+1)))=1,1,0))

Just for interest the =1 bit looks for Sundays 2 would be mondays etc

With
A1: (the start date)
A2: (the end date)

This formula counts the number of Sundays within that range
=SUM(INT((WEEKDAY(A1-1)+A2-A1)/7))

Note: To count different weekdays, replace 1 with
one of these values: 1=Sun, 2=Mon.....7=Sat

Does that help?
Post back if you have more questions.

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