In Access, the DateAdd function returns a date after which a certain time/date interval has been added.
The syntax for the DateAdd function is:
DateAdd ( interval, number, date )
interval is the time/date interval that you wish to add. It can be one of the following values:
Value Explanation
yyyy Year
q Quarter
m Month
y Day of the year
d Day
w Weekday
ww Week
h Hour
n Minute
s Second
number is the number of intervals that you wish to add.
date is the date to which the interval should be added.
For example:
DateAdd ('yyyy', 3, #22/11/2003#) would return '22/11/2006'
DateAdd ('q', 2, #22/11/2003#) would return '22/05/2004'
DateAdd ('m', 5, #22/11/2003#) would return '22/04/2004'
DateAdd ('n', 51, #22/11/2003 10:31:58 AM#) would return '22/11/2003 11:22:58 AM'
DateAdd('yyyy', -1, #22/11/2003#) would return '22/11/2002'
