What is the most common birthday in Japan?


Why is it that we get a little bit excited when we meet someone who shares the same birthday as us? Even if it’s our first time meeting, we end up feeling some kind of connection.

But there are some people out there who have yet to meet somebody with the same birthday as them.

Why is there such a difference?

The most common birthday in Japan is Christmas= December 25th
It seems so cool to have your birthday on Christmas. It’s making me jealous! Don’t you agree?

But a closer look at research done on births by the Ministry of Health, Welfare, and Labour reveals that December 25th actually has the highest number of births in Japan!

So what about the rarest birthday?
On the other hand, the rarest birthday in Japan was found to be on February 29th of leap years. This is hardly surprising since this date only appears on the calendar once every 4 years.

However, the second most rare birthday falls over the end of year and new year’s period. There are least births between December 31st and January 3rd.

Why is that?

This is because of the hospital systems.

Most people make adjustments so that they can avoid going into labour during that period. The hospital enters a holiday period at this time meaning there is less staff on call. Because of this, many people are inclined to organise a caesarian section before or after the holiday season.

On consideration it seems like an acceptable reason, but the answer itself is not all that exciting.


Distribution of birthdays throughout the year may also depend on culture and religion of any given country.
