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.

The New York rules in the agency’s own words, and every New York district
