Vanhojentanssit
Vanhojen tanssit or wanhojen tanssit in Finnish, de äldstes dag in Swedish, is a formal prom held in Finnish upper secondary schools during the second year. It is a celebration of when the second-year students become the seniors of the school. The prom is usually held the day after the third-year students stop attending school and start studying for their matriculation exams in February. The people attending the dances are called vanhat. Sometimes the first word is spelled with a w for a more archaic feel.
After the ball, the students sometimes attend a dinner in the evening, which is sometimes in a very formal restaurant.
