If the expected number is different from the actual number of canceled days, the beginning of summer vacation might be adjusted to keep the school year the same length . If there are too many canceled days, some districts will keep the beginning of summer vacation from moving too far by holding school during a scheduled spring vacation, or by holding school on Saturdays, professional development days, or other scheduled holidays . If the cancellation does reduce the number of days of instruction below the state minimum, the district may decide to simply drop the missed day from the academic year . </P>
