How common is your birthday?

Not all birthdays are created equal… in fact, for most countries in the north temperate zone, more people are born in summer (May – August) than in winter (October – January). This heatmap allows you to check how popular your birth date is. It shows the number of people in Belgium for each specific birthday.

There are some interesting outliers: January 1st and July 1st are extra common, because people with an unknown birth data are commonly assigned these birthdays. The national holidays (May 1, July 21, August 15, November 1 and 11, December 25) are clearly visible as dips in the data. And obviously, February 29th is also not very popular!

We haven’t figured out why more people are born on the 1st, 5th, 10th, 15th, 20th and 25th of each month, but possibly this has some administrative reasons as well…
