If one raises an obvious question like his, (s)he has to justify such a record is possible.
However, I came across a school certificate showing 30 Feb 1938 as the birthdate for an EB Employee. When we asked whether we could take 1 or 2 Mar as birthdate, Govt clarified that as per rules, the month is deemed to be known and therefore date of birth should be 16 Feb.
Some people say that years divisible by 400 should have 30 days in Feb. However, that did not happen in year 2000. Though there were speculations about this, I do not remember the authority who put it to rest.

Our custom is to celebrate Janma Nakshathrams only and not calendar dates. This is slowly on the way out.
Hindus believed that lights going out at important junctures were an inauspicious omen. But shooing candles off on the birthday cake is now considered normal procedure. Western influence!
People born on 29th Feb could celebrate their birthdays only once in 4 years. Therefore this habit of celebrating calendar birthdays would make them save some cash but forgo considerable happy moments.
