In Excel the DAY() function has an error in it.
Days up to March 31,2009 are correct ... but as of April 1,2009 the results
are 3 days off.
04/01/2009 should be "4" (wed) but shows as "1" (sun)

The Weekday function however is correct.
Anyone else get this same problem or is it my computer?
 
I think you're misunderstanding how the DAY() function works. It returns a
number corresponding to the day of the month (not week). So, 04/01/2009
should return 1, since it is the first day of the month.

You are Correct Elkar !
It just so happened that the data I used started with Feb. 1st 2009,
which is a Sunday, and so is Mar.1st and the function Day() actually
reported the correct day-of-week from 2/1/2009 on. Until April 1st -
which then gave me the unexpected result.
I didn't realize that the function, with formatting of "ddd",
continued to report multiples of 1,...,7 as the correct day-of-week!
Reviewing the function I saw I should have been using weekday()
instead.
Thanks for the feedback...
