Which November birthdays are rarest?
All 7 dates on which Thanksgiving can fall, November 22 through 28, are the seven least common November birthdays in this dataset. November 27 is the lowest of them. Its commonness rank is 359 among all 366 birthday dates, where #1 means most common.
That overall rank puts November 27 near the rarest end of the year, too. The full rare-birthday ranking shows how it compares with other months. You can use the table above to compare it with another November date, or check a birthday in any month.
Which November birthday is most common?
November 21 leads the month. It ranks 76 across all 366 dates. It had 19.0% more recorded births than November 27 over the 21-year period.
Every November date occurred 21 times in these records. Dividing each date's total by 21 would leave the order unchanged. To compare November as a whole with months of different lengths, see the birth-month guide.
Why are the dates near Thanksgiving low?
Thanksgiving is the fourth Thursday in November, so it moves among November 22 through 28. November 27, for example, was Thanksgiving in some of the years studied and a different weekday in others. A fixed-date ranking blends those years together.
Our Thanksgiving birth study follows the actual holiday each year and compares it with nearby Thursdays. That shows a lower count on Thanksgiving in these records. The November ranking by itself cannot tell us why any date has fewer births.
For the 2026 holiday, compare November 26 birthdays with November 27 birthdays, the Friday after Thanksgiving.
What about November 11 and November 13?
The November 11 guide separates Veterans Day from its federal observed date. The November 13 guide separates that date's rarity from its single Friday occurrence in the SSA study.
For Friday-the-13th events across all months, see the Friday-the-13th birth study.
How to read the ranks and counts
The November rank compares 30 dates; the overall rank compares 366. Both measure commonness, with #1 at the high end. Sorting the table from rarest first changes the row order, not the meaning of a rank. A date's birth share uses all recorded births in the dataset as its denominator, including births outside November.
We calculated the results from daily U.S. birth records compiled by FiveThirtyEight: CDC/NCHS for 1994 through 1999 and SSA for 2000 through 2014, without overlapping years. November accounts for 6,884,173 recorded births. These counts describe the historical records, rather than everyone alive now or births worldwide. The methodology explains the source coverage and calculations.
