Gentse Feesten

The Gentse Feesten is a festival in the city of Ghent (Belgium), and the largest of its kind in Europe. It starts on the Saturday before July 21 (the Belgian National Holiday) and it lasts ten days. The last day (always a Monday) is known as De dag van de lege portemonnees (The day of the empty purses) making allusion to the fact that many people have spent their money during the festival.
