Netherlands 36 hours is full time, i work 4x9 hours, so basically a 4 day workweek, for about 20 years now, used to work 38 and got paid extra for the effort. But soon found out more free time is priceless.

Belgium is 38 hours for instance.

In Europe they don't count their lunch breaks as hours worked. That's why the number is lower. If counted the European way then 09:00 to 17:00 Monday to Friday is actually 35 hours a week.
