The Fall and Spring terms consist of 15 and 17 lessons per term respectively, unless otherwise specified and agreed upon (ex: if you started a new class halfway through the term).
There are a few national holidays in each term which will coincide with lessons; on those days there will be no lessons held and they are already taken into account in the total number of lessons per semester (i.e. you don’t need to make up the lessons that would have occurred on those days). These dates will be blocked out in your attendance rosters as holidays with no lessons occurring. Also note that some schools may have the day before or after some holidays off as well, but you will be notified in advance if that is the case. Holidays can include:
Fall Holiday (Mon-Saturday Week 42)
Independence Day (6 Dec)
Ski Holiday (Mon - Saturday Week 8)
Easter (Thursday - Monday, dates change every year)
Vappu (1 May)
Helatorstai (Thursday in May, date changes every year)
