Eastern comes in March or April, depending on the year. The three Easter holidays are Good Friday, Easter Day and Easter Monday. Shopping can only be done with difficulty after the middle of this day. April begins with April's Fool's Day, a day for fooling the gullible. It is not a vacation day.
Festivities vary a bit in different parts of Sweden.
At Lule University a large Valborg bonfire is lit, a speach to Spring is delivered and a fireworks light up the late evening sky. VAlborg is also a shortened work day. Two church holidays are celebrated in May and early June. Although the next day is not a holiday, it is a vacation day for most people, including schools children. Whit Monday are church holidays and therefore also vacation days.
