I assume by  didn t work  you mean that it s giving you a timestamp instead of the formatted date  because you were doing it correctly    effectiveDate   strtotime   3 months   strtotime  effectiveDate       returns timestamp echo date  Y-m-d   effectiveDate      formatted version

Tchoupi s answer can be made a tad less verbose by concatenating the argument for strtotime   as follows    effectiveDate   date  Y-m-d   strtotime  effectiveDate     3 months         This relies on magic implementation details  but you can always go have a look at them if you re rightly mistrustful

Change it to this will give you the expected format    effectiveDate   date  Y-m-d   strtotime   3 months   strtotime  effectiveDate

You need to convert the date into a readable value  You may use strftime   or date     Try this    effectiveDate   strtotime   3 months   strtotime  effectiveDate     effectiveDate   strftime     Y- m- d     effectiveDate    echo  effectiveDate    This should work  I like using strftime better as it can be used for localization you might want to try it
