The first day of school, in most provinces, is on the Tuesday after the first Monday in September (the day after Labour Day), but varies based on the individual school boards. In some areas, including Newfoundland and Labrador, school begins for faculty and staff on the first Tuesday in September, but students are not required to attend class until the day after.
In Quebec, Cegep students start school the third week of August. Elementary and high school students start back the last week of August, anywhere from Tuesday - Thursday and on the rare occasion will start after Labour Day, depending on the school year. University students always start after Labour Day.
The first day of school is the first day of the academic school year. The first day of school for many school districts in various states is on the day after Labor Day (first Monday in September). On that day, public transportation services increase and start the rush hour earlier.
In some other school districts, school begins in mid- to late August. For instance, the Denver, Colorado metro area schools go back in mid-August and schools in the Cleveland, Ohio metro area start back usually one week before Labor Day. The Boston, Chicago, New York City, Philadelphia, and San Diego school districts start back the Tuesday or Wednesday after Labor Day.
Schools in Cleveland, Ohio used to start the school year the day after Labor Day, but in the 1976-77 and 1977-78 academic years, the school year was affected by several bad blizzards, brutal cold, and an energy crisis. In the 1977-78 school year, many school districts had to extend the school year almost to June 20.
In the 1978-79 school year, the Ohio General Assembly and the Ohio Department of Education moved the start of the year to late August, one week before Labor Day. This went into effect beginning in the 1980-81 academic year. In most school districts in Utah, the school year starts between August 25 and August 30, and goes until the last week of May or the first week in June.
