The November guide covers the full month. For the moving holiday later in November, the Thanksgiving study follows the actual holiday each year rather than treating one fixed date as Thanksgiving every time.
Veterans Day and its federal observed date
Veterans Day is November 11. Under the standard rules for federal employees who work Monday through Friday, a Saturday holiday is generally observed on the preceding Friday, and a Sunday holiday on the following Monday. The Office of Personnel Management explains these rules. They describe federal work schedules; they do not tell us when hospitals close or how deliveries are scheduled.
In SSA U.S. records from 2000 through 2014, November 11 itself was the federal observed date in 10 years. Its matched-weekday comparison was almost level in that group. The 5 weekend occurrences had a difference of +1.5% from nearby dates on the same weekday.
| Calendar group | Years | Occurrences | Births per occurrence | Control mean | Difference |
|---|---|---|---|---|---|
| Target is the federal observed date | 2002, 2003, 2004, 2005, 2008, 2009, 2010, 2011, 2013, 2014 | 10 | 12,782.4 | 12,783.5 | -0.0% |
| November 11 on a weekend; federal observed date differs | 2000, 2001, 2006, 2007, 2012 | 5 | 8,172.6 | 8,050.7 | +1.5% |
| Veterans Day federal observed date (November 10, 11 or 12) | 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 | 15 | 12,693.4 | 12,768.3 | -0.6% |
The last row follows every federal observed Veterans Day, including November 10 or 12 when the observance shifted. Its difference is -0.6%. It shares years with the first two groups and repeats their weekday November 11 observations, so do not add the rows together. These small, mixed differences do not establish a strong holiday effect.
How does it compare with nearby weekdays?
For each November 11 in the SSA period, we consider dates one and two weeks before and after it. Those dates share its weekday. We exclude actual and standard observed federal holidays, Christmas Eve, December 26 and the Friday after Thanksgiving. Here, we exclude November 25 when it falls on Thanksgiving or the Friday after it.
The remaining 56 control dates give a pooled difference of +0.4%. November 11 is below its nearby mean in 8 years and above it in 7.

Using only the one-week comparisons gives +0.3%; using only the two-week comparisons gives +0.7%. Both use 15 target years. We average eligible controls within each year, then compare summed target births with summed annual means. The downloadable analysis lists the exact included and excluded dates.
Sources and what this birthday rank covers
The FiveThirtyEight source files provide CDC/NCHS records for 1994 through 1999 and SSA records for 2000 through 2014. We exclude overlapping CDC years; annual comparisons use SSA alone.
