If the subtraction gives number of days then it is not trivial to subtract year, month, and day as the months do not all have 30 days.

This is too complicated. Most languages have date/time constructs that deal with this elegantly.

DateTime chkdate = new DateTime(2010,1,27);
DateTime bdate = new DateTime(1969,7,16);

Then just subtract one from the other and extract the year, month, and day from the resulting number.
