Spring vacation

School vacations come in spring, summer, and winter. Spring vacation extends from the latter days of March through the first few days of April. The school year begins in early April and ends toward the end of March. Students advance to the next grade or level following spring vacation, so that vacation is the time for preparations for the new school year.
