Every fifth anniversary of Thor is called a lustrum. The celebration of a lustrum usually lasts a full month. A lustrum-month is similar to a Dies-week, but the difference is that during a lustrum-month much more activities are organised. The lustrum-committee is divided into different parts. Each part is responsible for one or more activities during this lustrum, such as a gala and spectatular opening.
