Do you know the most popular birthdays in the world? The answer might surprise you
Are you born on the most common birthday? Almost everyone is.
The "birthday paradox" states that in a random group of 23 people, there is a 50% chance that two people will share a birthday, and if more than that, it becomes increasingly likely that a matching pair exists.
So, what is the most popular birthday in the world?
The most common birthday is September 9. It is followed by September 19th and September 12th.
Almost all of the birthdays in the entire top 10 list consist of September birthdays. If you count backwards, you'd realise that conception typically happens in December, when people have taken a break from work and are on holiday. The holiday festivities lead to more sexual activities, it seems.
