The Maryland rule

How Maryland counts a lost day

Maryland requires at least 180 school days and 1,080 hours within 10 months, with days of at least 3 hours. On a county board's application showing it tried to comply, the State Board may shorten the year when severe weather or a disaster prevented normal attendance, without cutting state or local funding.
