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.
