CANADA TIME ZONESCanada uses six primary time zones. From east to west they are Newfoundland Time Zone, Atlantic Time Zone, Eastern Time, Central Time Zone, Mountain Time Zone, and the Pacific Time Zone. Daylight Saving Time begins at 2:00 a.m. local time on the first Sunday in April. On the last Sunday in October area on Daylight Saving Time fall back to Standard Time at 2:00 a.m. The names in each time zone change along with Daylight Saving Time. Eastern Standard Time (EST) becomes Eastern DaylightTime (EDT), and so forth. Some areas of Canada not using Daylight Saving Time include, Fort St. John and Dawson Creek in British Columbia, Creston in the East Kootenays, most ofSaskatchewan (except Denare Beach and Creighton) and Atilokan in Ontario. GMT is the code for (Greenwich Mean Time) also called UTC = Coordinated Universal Time. The (-9h) in Alaskan Standard Time refers to that time zone being nine hours behind UTC or GMT and so forth for the other Time Zones.In Canada, Time Zones and Daylight Saving Time usually have been regulated by provincial and territorial governments. Clocks are turned forward by one hour on the first Sunday in April and turned back on the last Sunday of October. Time Zones have been like this since 1988.From east to west, Canada isneatly divided into six time zonesEarth is divided into 24 time zones (for the sticklers out there, I know there are really 28, but the extra 4 are unusual). As you move westward, each time zone you enter is one hour earlier thanthe time zone you are leaving (until you get to the International Date Line, but that's another story). As an example, if you were driving west through the state of Kansas in the Central Standard Time zone of the United States and you were about to enter the state of Colorado in the Mountain Standard Time zone you would have to set your watch back one hour. So, if your watch said 3:30 p.m., you would need to change it to 2:30 p.m. Because of these time zones the rotation of the Earth allows some sky phenomena to occur at essentially the same time (+/-30 minutes) no matter where you are on the planet. This basically includes the times of when certain constellations will rise above your horizon. Here is another example. Time zones span quite a large distance and there is a reason why I noted above that the times are essentially accurate to within +/-30 minutes. Let's say you are on the eastern
borderof the Central Standard Time zone. Sunrise occurs at 5:00 a.m. For people further west, however, the sun has not risen yet. Why? Because Earth is round and sunlight does not curve around Earth's limb. The Earth continues to rotate and in the middleof the Central Standard Time zone the sun will rise at 5:30 a.m. More rotation and then the western edgeof the Central Standard Time zone sees the sun rise at 6:00 a.m. You can see here that, if this were to continue, sunrise would occur at noon over the Pacific Ocean and at 6:00 p.m. for people in Asia, but this does not really happen because of the time zones.If you were standing on the western edge of the Central Standard Time zone and walked or drove westward into the Mountain Standard Time zone, you would have to set your watch back one hour. So now a person standing on the eastern edgeof the Mountain Standard Time zone sees the sunrise at 5:00 a.m. The cycle essentially repeats through every time zone. So, whenever you see the term "local time" on this web site this basically means your time.Time zonesWhether you're travelling east or heading out west, working out the time differences can be a bit confusing. Here's our simple guide to knowing the time on your travels. The earth is divided into 24 time zones, each of which is about 15° wide. Each time zone is one hour differentto the next. Withineach zone all clocks are set to the same time. This is the case all over the world; there are very few exceptions such as South Australia, where there are half-hour zones.The middle line, or meridian, is located in Greenwich in London. All time zones arebased around Greenwich Mean Time. Each time zone to the west of Greenwich is on an earlier time zone; whilst those to the east of Greenwich is on a later time. Here are two examples: Berlinis located one time zone eastof London so is one hour aheadofGMT. When it is midday in London its 1pm in Berlin. Los Angelesis 8 time zones westfrom Britain, so is eight hours behindGMT. When it is midday in London its 4am in Los Angeles. Directly around the globe from Greenwich is theInternational Date Line,this is where the time zones meet. The Date Line is twelve time
