Quick answers

How many babies are born on February 21?

About 10,652 a year in the United States. It was at its most common in 1973, when 9,342 babies were born and it ranked #55 of 365; at its rarest in 1988, with 8,422 births at #355.

Is February 21 a common birthday?

In the United States, February 21 is the 116th rarest of 366 dates, with about 10,652 births a year. That makes it an ordinary birthday: neither rare nor especially common.

What is the rarest February birthday?

In the United States, February 29: the 14th rarest of all 366 dates, with about 9,906 births on each February 29. The most common February birthday is February 14, the 94th most common of the year.

How precise is the ranking?

In the middle of the calendar it is not exact. 93 other dates are within 1% of February 21's count, spread from #203 to #296, so the position inside that group would shift with a different set of years. That band is the accurate answer; the rank is the simple one. At the ends — Christmas Day, New Year's Day — nothing is close.

Is February 21 rarer in other countries?

In some. It is rarer in 11 of the 26 other countries we hold daily records for. It is at its rarest in Costa Rica, at #357 of 366, and at its most common in Peru, at #26.
