The Prince William County School Board voted unanimously October 18, 2017 to adopt a 2018-19 school calendar that begins with a pre-Labor Day opening (School opens August 27) and ends with the last day of school on June 11. The pre-Labor Day start is made possible by qualifying for a waiver to Virginia's usual ban on pre-Labor Day holiday starts to the school year.

The Prince William County School Board originally approved the 2019-20 calendar on October 17, 2018 to adopt a 2019-20 school calendar that begins with a pre-Labor Day opening (School opens August 26) and ends with the last day of school on June 12. The calendar includes two full weeks at Winter Break. The calendar was modified on April 3, 2019 by the Prince William County School Board in response to a change in Virginia law that no longer requires waivers to start before Labor Day but now requires that the Friday before Labor Day (August 30) be a holiday. The calendar now includes that day as a holiday, making the Labor Day weekend a four-day weekend.
