actually it is just odd-even year..
if i have 21 April 1989 which is an odd year, i should have 21 April 2013.
20 May 2010 is even, so i should have 20 May 2012. If this is 01-Jan-2014, than it must return 21 April 2015 and 20 May 2014..

Thanks for advance..

You may use the MOD operator, for instance, try:

SQL

select MAKEDATE(2012 + MOD(YEAR("1989-04-21"),2), DAYOFYEAR("1989-04-21"));
