The most popular birth date is October 5th which is about 9 months after New Years Eve. For some reason April 21st is also popular.
The least common birth date is February 29 (only one every four years) followed by May 22.
NOTE
The most common length of pregnancy (37 to 42 weeks) has a median of 39.5 weeks, or 276 days, and October 5th is the 278th day. Using the US figure of 38 weeks, September 23rd would be the likeliest day for New Year's babies.
According to one source, October 10th is the most common birthday!
Conversely, August is the most common birth month!
Other sources, which may simply be parroting one another, say October 5th. This may just be an extension of the human pregnancy cycle beginning near the start of the year. If New Years' celebrations were the source, births should peak on September 23, the 266th day (38th week) of the year.
For Americans, it is October 5th.
It has been speculated that this is because a large number of children are conceived during holiday celebrations. However, this would bring the bumper crop of babies before September 23 (day 266), 38 weeks after New Year's Day.
Correction: Oct. 10th is the most common birthday! based on the records of 244 millions of registered Amercans. Here there are more details:
