The New York rule

How New York counts a lost day

New York requires 180 days of session plus 900 hours a year for kindergarten to grade 6 and 990 hours for grades 7 to 12. The Commissioner can excuse up to 5 days closed for extraordinary weather, but only if the district cannot make them up by using all its scheduled vacation days before the June Regents exams.
