![]() ( See also Daylight Saving Time in Canada.Galvano-Magnetic 24 Hour Clock, Royal Observatory, Greenwich. It was introduced in Canada by the federal government in 1918 as a measure for increasing war production, emulating legislation in GermanyĪnd Britain. A pre-breakfast daylight hour can be “saved” for use after supper by the practice of turning the clocks ahead by one hour in the spring and setting themīack by one hour in the autumn. In Canada, as in many middle-latitude countries, Daylight Saving Time (DST) is now commonly used. Minutes from the neighbouring time zones, as opposed to one hour. In Newfoundland, for example, the time zone differs by 30 The boundaries conform to more convenient geographical or political boundaries. For example, British Columbia time in the winter months is described as UTC-8h, meaning it is eight hours behind Coordinated Universal Time, while Newfoundland time is referred to as UTC-3h30.Ĭanada, like the rest of the world, now uses a modified version of the time zones created by Sir Sandford Fleming. Time zones in Canada are referred to as UTC- xh. Today, the implementation of Greenwich Mean Time is officially referred to as Coordinated Universal Time, or UTC. Zones around the world, each 15° of longitude wide, with the first centred on the Greenwich meridian. The conference agreed on Greenwich, England, as the common reference for longitude and time, and attending countries rapidly implemented Fleming’s plan of 24 time Fleming’s advocacy of time zones had its greatest effect in 1884 at an international conference in Washington, DC, called to select a prime meridian to be used for In 1883, North American railways adopted hour-wide time zones. Fleming became a strong advocate of time zones to be usedįor all purposes. To reduce the remaining confusion at a union station, where all the lines converged, American Charles Ferdinand Dowd advocated geographic time zones for the railways. North American railways experimented with operatingĮach line on uniform time. ![]() England was the first country to adopt standardized time, with the railways forcing the issue. William Hyde Wollaston and Abraham Follett Osler promoted a system of universal time. Although many other travellers likely had similar experiences, Fleming’s personal experience seemed to inspire his search for a way of reducing confusion He became chief engineer for the Canadian Pacific Railway, Sir Sandford Fleming spent one uncomfortable night in a railway station due to the time confusion when changing trains. However, with the advent of railways, the multitude of municipal times became a significant aggravation for travellers. Everyone agreed on this arrangement when an 18 km journey was considered long, arduous, unpredictable or rare. For example, at a latitude of 49°, two municipalities would have differed in time by one minute for each 18 km of east-west separation, with the easternmost municipality having the Up to the 1880s, municipalities used their own local mean solar time. Sir Sandford Fleming and Greenwich Mean Time ![]() The official time reference for Canada comes from the National Research Council of Canada (NRC), but, except during wartime, the provinces and municipalities legislate the official time zone boundaries. Similarly, Saskatchewan follows CST year-round and, as of 2020, Yukon follows PDT, also known as Yukon Standard Time, year-round. Boundaries shift because some municipalities choose not to participate From the second Sunday in March to the first Sunday in November most of Canada follows daylight saving time.Ī portion of northeastern British Columbia in the summer, but not during the winter (see maps below). Referred to as standard time zones, and may be abbreviated as PST, MST, CST, etc. Similarly, Saskatchewan follows CST year-round and, as of 2020, Yukon follows PDT, also known as Yukon Standard Time, year-round. For example, the Mountain time zone includesĪ portion of northeastern British Columbia in the summer, but not during the winter (see maps below). The boundaries of the standard time zones are not necessarily the same as those of the corresponding daylight saving time zones. From the second Sunday in March to the first Sunday in November most of Canada follows daylight saving time.ĭuring this summer period the time zones may be abbreviated as PDT, MDT, CDT, etc. ![]() From the first Sunday in November to the second Sunday in March these zones are From west to east these time zones are: Pacific, Mountain, Central, Eastern, Atlantic and Newfoundland. There are six time zones in Canada covering four and a half hours.
