Be careful about your definition of "correct" - many leap day babies
celebrate their birthday on Feb 28.
For many years I worked for a large life insurance company - in this leap
day instance we generally picked the day that would be most favorable to the
customer. If being at a lower age meant you qualify for a lower rate then
we used March 1 but if you had to obtain an age to receive a benefit then we
used Feb 28.
