As of March 3, Fairfax County schools have used eight snow days, along with five two-hour delayed openings for a total of 58 hours used, says district spokesman John Torre.
“FCPS has received additional guidance from the state regarding makeup days and the state has indicated that FCPS does not have to make up two of the eight days missed thus far giving FCPS a total of 32 extra hours, or about five snow days remaining, before any missed days would need to be made up,” Torre writes in an email to WTOP.
