What is the most common birth month for all NHL players in history?

This is animated representation of most common birth month for all NHL players that ever played, exactly 7982 of them.

As we can see, the most common birth month is January and least common is December. Even more interesting is that 29.75 % of all players are born in the first quarter of the year, and 20.5 % in the last quarter of the year.

This is known as Relative age effect:
The term relative age effect (RAE), also known as birthdate effect or birth date effect, is used to describe a bias, evident in the upper echelons of youth sport and academia, where participation is higher amongst those born early in the relevant selection period (and correspondingly lower amongst those born late in the selection period) than would be expected from the normalised distribution of live births.
