In most schools, the school week consists of days Monday through Thursday or Friday. However, in a few countries it goes from Monday to Saturday. There is no school on Sundays, and some afternoon classes may be cancelled or skipped. A few schools are cancelling Fridays, due to fuel costs. In Japan the school week is Monday to Friday (though the majority of students in Japan go to school on Saturdays and Sundays for test preparations, athletics, etc.).
