In the part of Québec east of the meridian of 63 degrees west longitude:
- the legal time is Atlantic Standard Time, which is four hours behind Coordinated Universal Time (UTC – 4 h).

- The meridian of 63° west longitude runs just east of Havre-Saint-Pierre, cuts through Île d'Anticosti roughly in the middle and continues between the Gaspésie region and Îles-de-la-Madeleine.
The largest portion of Québec, in terms of both area and population, is located to the west of the meridian of 63° west longitude.
The portion of Québec located to the east of the meridian of 63° west longitude consists of:
- A portion of the Minganie region, including Baie-Johann-Beetz, Aguanish, Natashquan, the eastern half of Île-d’Anticosti and a portion of the unorganized territory of Lac-Jérôme;

An angular distance on the earth's surface, measured east or west from the prime meridian at Greenwich, England, to the meridian passing through a position, expressed in degrees (or hours) minutes, and seconds. Longitude ranges from 0 to 180 degrees west or east.
An imaginary circle passing through any place on the earth's surface and through the North and South geographic poles and used calculate longitude. Forming a right angle with the equator, the meridians divide the earth's surface into 360 large circles crossing the North and South poles. The most well-known meridian at 0º longitude is that of Greenwich, England, which served for a long time as the international reference for setting time.
Coordinated Universal Time
Coordinated Universal Time (UTC) replaced Greenwich Mean Time and is used to establish the legal basis for calculating time throughout most of the world. In its role as the zero-point reference, it serves for all events, whether meteorological or other. UTC is the standard time common to every place in the world. This characteristic is essential when charting the weather, for example, for several time zones at once.
