Questions

Quick answers

How many babies are born on March 15?

About 10,729 a year in the United States. It was at its most common in 1994, when 12,298 babies were born and it ranked #45 of 365; at its rarest in 2009, with 7,049 births at #359.

Is March 15 a common birthday?

In the United States, March 15 is the 149th rarest of 366 dates, with about 10,729 births a year. That makes it an ordinary birthday: neither rare nor especially common.

What is the rarest March birthday?

In the United States, March 13: the 22nd rarest of all 366 dates, with about 10,340 births a year. The most common March birthday is March 1, the 147th most common of the year.

How precise is the ranking?

In the middle of the calendar it is not exact. 94 other dates are within 1% of March 15's count, spread from #173 to #267, 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 March 15 rarer in other countries?

In some. It is rarer in 14 of the 26 other countries we hold daily records for. It is at its rarest in Hungary, at #355 of 366, and at its most common in Brazil, at #9.
