Happy birthday tomorrow. I think it's just a coincidence that they share the same birthday month.

I've always found the biggest concentration of birthdays to be in early September.

For my family, most birthdays are sometime around August.

For some random reason, October 5th is the most common birthday. September is probably the most common birth-month, followed by October, I believe.

I would assume that birthdays are pretty much evenly spread around the year ... ?

half of my mothers family has a birthday in november, meanwhile my birthday is in march and my brothers isin october

It's coincidence, nothing more.

To further prove my point of there being so many birthdays between Christmas and new year:
