The Dutch academic year officially starts on the last Monday of August and is effectively 42 weeks long. The academic year is built up of two semesters of each 21 weeks. The semester switch takes place at the end of January.
There are a few breaks in the course of the academic year, which are not included in the 42 study weeks. The summer holidays therefore do not start until mid July.
Study programmes may deviate slightly from the official opening and closing dates of the academic year. Check the information that you will receive from your department or check with the ISO for the academic calendar of your study programme.
