Leap Year Birthday Checker
Born on 29 February? Work out how many real birthdays you have had, and which generation you are in.
A child born on 29 February 2016 has had two real birthdays by 2026 and the next falls in 2028, because a leap-day birthday recurs only every four years — about a quarter of the birthdays other children have.
