Hi Tim,

One way:

=DATE(YEAR(A1)-1,MONTH(A1),DAY(A1))

Hi All,

Its the end of a long week here and my brain has already shut-down for
the weekend.

can someone tell me how i can subtract one year from a date. eg, if the
initial date is 19/09/2006 in cell A1 how do i calculate to get the
result of 19/09/2005 in cell B2? i need to do this for two sets of
approx. 3000 dates.

i can't think what formula or vba i would use even though it seems soooo
simple! i can't simply subtract 365 days because some might be in a leap
year.

tia,

Tim
