please suggest, how can this?

agsm's answer shows convenient way of solving problem using python-dateutil package. if don't want install package? solve problem in vanilla python this:

from datetime import date  def add_years(d, years):     """return date that's `years` years after date (or datetime)     object `d`. return same calendar date (month , day) in     destination year, if exists, otherwise use following day     (thus changing february 29 march 1).      """     try:         return d.replace(year = d.year + years)     except valueerror:         return d + (date(d.year + years, 1, 1) - date(d.year, 1, 1)) 

if want other possibility (changing february 29 february 28) last line should changed to:

        return d + (date(d.year + years, 3, 1) - date(d.year, 3, 1))
