How to solve timezone? ›

There are actually six time zones in the USA. The four main ones are Eastern, Central, Mountain, and Pacific Standard Time. The two others are Alaska Standard Time and Hawaii-Aleutian Standard Time, observed only by Alaska and Hawaii respectively.

A time zone is an area on Earth that has a specific time that all citizens can set their clocks to. Different time zones exist as you move from east to west (or west to east) on the surface of the earth. The farther you travel, the more time zones you'll pass through.

By 1929, the majority of countries had adopted hourly time zones, though some countries such as Iran, India, Myanmar and parts of Australia had time zones with a 30-minute offset. Nepal was the last country to adopt a standard offset, shifting slightly to UTC+05:45 in 1986.

The opposite line of longitude to the Prime Meridian is the International Date Line, which is where the calendar changes by a day. Calculating time zones is simple and involves adding or subtracting an hour for every 15 degrees of longitude.

To convert 18:00 UTC (6:00 p.m.) into your local time, subtract 6 hours, to get 12 noon CST. During daylight saving (summer) time, you would only subtract 5 hours, so 18:00 UTC would convert to 1:00 p.m CDT. Note that the U.S. uses a 12-hour format with a.m. and p.m. Other countries use 24-hour time.

Add the local time offset to the UTC time. For example, if your local time offset is -5:00, and if the UTC time is shown as 11:00, add -5 to 11. The time setting when adjusted for offset is 06:00 (6:00 A.M.).

In the U.S., Hawaii and most of Arizona, as well as some territories, do not observe daylight saving time. Australia, Brazil and Canada are similar. For example, in Australia, daylight saving is not observed in Queensland, the Northern Territory, Western Australia, Christmas Island or the Cocos (Keeling) Islands.

You can see that the most extreme time zones are +14 hours at Line Islands (Kiribati), and -12 hours in and around Baker Islands (US). Therefore, the maximum possible difference between times on Earth is 26 hours. That means that at 11:00 PM of a Monday in Baker Island, it is 1:00 AM of a Wednesday in Line Islands.

It is also referred to as the "latest time zone" on Earth, as clocks in it always show the 'latest' (i.e., most advanced) time of all time zones. UTC+14:00 stretches as far as 30° east of the 180° longitude line and creates a large fold in the International Date Line around the Pacific nation of Kiribati.

Alaska • Time zones: Hawaii-Aleutian time and Alaska time • Alaska used to have four time zones. In 1983, however, the government consolidated the time zones to two: Hawaii-Aleutian time, which applies to the westernmost Aleutian Islands, and Alaska time for the rest of the state.

None of the 50 US states have three time zones. However, there are some states with two time zones. These are: Alaska (Alaska and Hawaii-Aleutian)

How many time zones are there in the US? There are six time zones in the US main country. The 50 US states are spread across the six standard time zones. With dependencies (inhabited and uninhabited), however, the total count comes to 11 time zones.
