If she was born on Feb 29th in a year that was 4 years before a century whose first two digits are not evenly divisible by 4.

For example.....if she was born on Feb 29th, 1896.....4 years later will not be a leap year because 1900 has its first two digits = 19.....and this is not evenly divisible by 4.

So...her "first" birthday will be on Feb 29th, 1904......eight years after she was born  !!!!!!!

I didn't know that Chris.

If the first 2 digits if a new century are not divisable by 4 then it will not be a leap year.

Cool!  Thanks.
