Today, Belgium uses a 12-month calendar thanks to a long history that goes back to Roman times. At that time, a calendar was created by Julius Caesar, the Julian calendar. That calendar already had 12 months, just like today. But it lagged behind the sun a little bit every year, and that caused problems after hundreds of years. Holidays such as Easter fell on the wrong date.

To solve this, Pope Gregory XIII had a new calendar created in 1582: the Gregorian calendar. It corresponded better with the solar year. In the same year, the new calendar was introduced in the Catholic countries, including the Southern Netherlands – the area that is now Belgium. Since then, Belgium has used this 12-month calendar, just like most of the world.
