Formula for weeks
 

I was wondering if there is a formula to calculate how many weeks it is from
today to a certain date

Formula for weeks
 

This formula will calculate how many days
=DATEDIF(Date1,Date2,"d")

or =DATEDIF(A1, B1,"d") with dates in A1 and B1

If by week you mean any seven days (not a Sun to Sat) then
=DATEDIF(A1, B1,"d") /7

best wishes

Hi,

Try this which wil return whole wee and a decimal for the part week

=ABS((DATE(2009,1,2)-TODAY())/7)

or this to return whole weeks rounded down

=INT(ABS((DATE(2009,1,5)-TODAY())/7))

You can use cell references for the dates

Or you could use:

=B1-A1

or

=(B1-A1)/7

Ah but that would be too simple for me after 3 hours tutoring calculus!
Yes, my answer was stupid!

I always wondered by "they" bothered with the "d" option in DATEDIF. But the
function is apparently broken in 2007 SP2 so I've generally stopped
recommending it for anything.

Now I have to edit my various sheets that use it <sigh.
