Hello,

Assume your date starts in A2 to down & you need to count the dates other than Friday between A2 & today()

B2, copy down

SUM(INT((WEEKDAY(A2-{1,2,3,4,5,7})+TODAY()-A2)/7))

Hi dear the above i tried but i got result as 5 digit numbers in all cells,

any how thank you for you feedback.

i got the answer with below formula
=round(today()-A2+1-INT((WEEKDAY(A2-6)+today()-A2)/7),0)

Why are you using ROUND? If A2 is a date (with no time) then you don't need that function...

Haseeb's solution should also work OK

[naveen marapaka]

its with time dear, since we pull out report daily basis which consisits of date with time.
so i used round function.

[daddylonglegs]

OK but if A2 contains a time and date then I don't think your suggested formula works consistently, e.g. you can get different results even if the date is the same. For example if today is Sunday 5th June then if A2 contains Friday 3 June 2011 09:00 then the result is 2 but if you change the time to 13:00 the result is 1

If you use this version

=TODAY()-INT(A2)+1-INT((WEEKDAY(A2-6)+TODAY()-INT(A2))/7)

Then you'll always get the same result for the same date, e.g. the above will always give 2 if the date is Friday 3 June
