Not counting its unincorporated overseas territories, the United States is divided among seven different time offsets from March to November (whole hours UTC-10 through UTC-4) and six different time offsets from November to March (whole hours UTC-10 through UTC-5).

There are five time zones in the US.
Five time zones are in the continental United States from west to east: pacific, mountain, central, eastern, and Atlantic.
The US does have six time zones. Starting from the West they are Hawaii-Aleutian, Alaska, Pacific, Mountain, Central and Eastern Zones.
Time zones were officially established in the US on November 18, 1883 by the railroads in order to standardize schedules. This was known as the Standard Time Act, which divided the US into four time zones: Eastern, Central, Mountain, and Pacific.
The US has several time zones, you would have to say which time zone you are referring to.
Canada uses 6 primary time zones, Unlike the United States that uses 9 primary time zones. ALL time zones go from east to west. CANADA'S TIME ZONES ARE: * Newfoundland * Atlantic * Eastern * Central * Mountain * Pacific UNITED STATES' TIME ZONES ARE: * Atlantic * Eastern * Central * Mountain * Pacific * Alaskan * Hawaii-Aleutian * Samoa * Chamorro The US and Canada have 5 time zones in common. Since there are more then one time zones within Canada and the US, we can't just say "The difference is ______" and give you a straight answer. Canada and the US have different time zones and they were listed. EDIT: Depending on whatever time zone or country (US or CANADA) you are in, the difference should be asked between the two time zones. EXAMPLE: "What is the time difference between Eastern time to Hawaii-Aleutian time?"
In the US there are six time zones, they have names they are called in the US and also have Greenwich Mean Time (GMT) Zone names: * US Eastern Standard Time = GMT - 5 * US Central Standard Time = GMT - 6 * US Mountain Standard Time = GMT -7 * US Pacific Standard Time = GMT - 8 * US Alaska Standard Time = GMT - 9 * US Hawaii-Aleutian Standard Time = GMT -10 In Summer most states in the six US time zones observe Daylight Savings Time and then the name of the zone would be, for example, US Eastern Daylight Time Zone.
One way to remember the time zones that cover the US is to use the acronym "EST CST MST PST" which stands for Eastern, Central, Mountain, and Pacific Standard Time zones. You can also remember that the time zones move from east to west across the country.
