Questions

Quick answers

How many babies are born on May 13?

About 10,376 a year in the United States. It was at its most common in 1975, when 9,247 babies were born and it ranked #78 of 365; at its rarest in 2018, with 6,618 births at #363.

Is May 13 a common birthday?

In the United States, May 13 is the 26th rarest of 366 dates, with about 10,376 births a year. That puts it on the rarer side of the calendar.

What is the rarest May birthday?

In the United States, May 27: the 20th rarest of all 366 dates, with about 10,322 births a year. The most common May birthday is May 24, the 105th most common of the year.

How precise is the ranking?

In the middle of the calendar it is not exact. 28 other dates are within 1% of May 13's count, spread from #321 to #349, 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 May 13 rarer in other countries?

No. May 13 is more common in all 26 other countries we hold daily records for than it is in the United States. It is at its rarest in New Zealand, at #335 of 366, and at its most common in Portugal, at #31.
