The Michigan rule

How Michigan counts a lost day

Michigan requires at least 180 days and 1,098 hours of pupil instruction. The first 6 days (or the same hours) lost to conditions outside the district's control, such as severe storms, are counted as instruction; up to 3 more can be approved by the State Superintendent.
