There are some days when it might seem like everyone has a birthday. When there is a snowstorm, then you might find that there are more births in September or October.
There are some births that are more common about nine months after a holiday, like New Years or Valentine’s Day. There is one birthday that is the most common in the world. It’s one that falls in the month of September as well.
The date for the most common birthday is September 16. There is a little bit more than a coincidence that explains why this is the most common day. The days before and after are common as well. There are actually 10 days in the month of September that are among the most common for the entire year.
If you look at a calendar, you will see that December is nine months before September. There are special events in December, such as Christmas and New Years, that often lead to couples being intimate.
This is also a time when areas of the country and the world begin to see snow and ice storms that can keep people inside their homes. This can lead to a couple being intimate if there is nothing else to do in the home and there’s no way to go anywhere.
