Questions

Quick answers

How many babies are born on October 13?

About 10,521 a year in the United States. It was at its most common in 1970, when 11,236 babies were born and it ranked #44 of 365; at its rarest in 1991, with 8,700 births at #352.

Is October 13 a common birthday?

In the United States, October 13 is the 64th rarest of 366 dates, with about 10,521 births a year. That puts it on the rarer side of the calendar.

What is the rarest October birthday?

In the United States, October 31: the 11th rarest of all 366 dates, with about 9,798 births a year. The most common October birthday is October 1, the 71st most common of the year.

How precise is the ranking?

In the middle of the calendar it is not exact. 66 other dates are within 1% of October 13's count, spread from #264 to #330, 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 October 13 rarer in other countries?

In some. It is rarer in 7 of the 26 other countries we hold daily records for. It is at its rarest in Brazil, at #356 of 366, and at its most common in New Zealand, at #55.
