The Pennsylvania rule

How Pennsylvania counts a lost day

Pennsylvania requires either 180 days, or hours: 900 for kindergarten through grade 6 and 990 for grades 7 to 12, as the district chooses. The state forgives no days; districts are expected to build make-up days into the calendar for closures beyond any Flexible Instructional Days.
