In 2016, the cheese market in Alkmaar takes place every Friday from 10:00 a.m. until 12:30 p.m., on the Waagplein, from March 25th until September 2nd. In 1365, the city owned one cheese scale; in 1612 there were already four. The founding date of the cheese carriers' guild is June 17th, 1593. The market has always taken place on the Waagplein. This square has been enlarged multiple times; over two centuries, it was enlarged no less than eight times, until it reached its recent size. Here, the importance of the cheese trade to the city becomes apparent. In the 17th century, cheese was traded from May until All Saints' Day, on Fridays and Saturdays. In the 18th century this was even extended to four days per week.
