Checked Oct 1, 2026: the district's calendar does not print a total of school days, so we compared our count with the 180 school days required by South Carolina law. They match. How we check.
Districts sometimes revise their calendars, and make-up days depend on weather. Confirm with Anderson School District One before booking travel.
