Canada is divided into five time zones: Mountain, Central, Eastern, Atlantic and Newfoundland time. Many areas of the country's provinces and territories operate on standard time from the first Sunday in November to the second Sunday in March and daylight saving time the rest of the year.
The divisions between time zones are based on proposals by Scottish Canadian railway engineer Sandford Fleming, who pioneered the use of the 24-hour clock, the world's time zone system, and a standard prime meridian.
