We don't have spring break, but every school has Easter break and it's always a week, either before or after Easter.
Except for Xmas and New years, every holiday in Sweden is in the spring or early summer. Other than Easter we have Christ-flew-to-heaven-day, 1st of May, National day and midsummer. We also used to have second day of Pentecost, but that was traded for National day about 10 years ago.
(A secular holiday instead of a christian one, Paul!!)
