Hi,
I am confused, 1/1/07 was a Monday and surely it should give 2007_w01 for
this?

Hi,

The answer your getting depends on what you have in cell M2. For 1/1/07 it
will correctly return week 53 and for 2/1/07 it rolls over to week 1.

Hi,
I am using Excel 2003 and am using this formula for converting dates
(21/07/2003)
to the following format 2003_w30. But for 2007 instead of giving me 2007_w01
I get 2006_w53, can some have a look at the formula and correct it?
=YEAR(M2)&TEXT(WEEKNUM(M2-1),"""_w""00")
