Assume cell A1 is your base date.

Enter this formula in B1 and copy across as needed:

=IF(COUNT($A1),A1-1,"")

Format as Date

Hi,

If i have a date, say 10/07/2009 and i want to have a series of cells next
to it that return the previous weekday, say 09/07/2009...and then if i
change
the first cell, all of the corresponding cells update. Thanks everyone.
