If the degrees between two points are known, then the number of degrees needs to be divided by 15 to get the difference in hours. If John lives at 120 degrees and Bob lives at 80 degrees, the difference is 40 degrees. 40 divided by 15 is just under 3 hours. That means they live two time zones away from each other.

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.

The United States uses nine time zones. From east to west they are Atlantic Time Zone, Eastern Time Zone, Central Time Zone, Mountain Time Zone, Pacific Time Zone, Alaska Time Zone, Hawaii-Aleutian Time Zone, Samoa Time Zone and Chamorro Time Zone.

How Many Time Zones Are There in the US? There are 9 time zones by law in the USA and its dependencies. However, adding the time zones of 2 uninhabited US territories, Howland Island and Baker Island, brings the total count to 11 time zones. The contiguous US has 4 standard time zones.

Calculating Local Time Using World Time Zones

The twenty-four time zones correspond to meridians of longitude. Specifically, the zones are spaced 15 degrees apart, and each time zone differs from its adjacent time zone by one hour (earlier or later).

The only parts of the US that do not have Daylight Saving Time (DST) are Hawaii, most of Arizona, Puerto Rico, the US Virgin Islands, the Northern Mariana Islands, Guam, and American Samoa. Arizona experimented with the change beginning in 1918 but decided to opt out of DST in 1968 permanently.

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.

What time zone is faster? ›

The time zone furthest ahead of EST…and, for that matter, all other time zones is UTC+14 (UTC+14:00 - Wikipedia). No one might suppose that the most offset in hours from UTC (or GMT, loosely speaking) would be 12. However, the mid-Pacific nation of Kiribati had a problem.

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.

Universal Time Coordinated (UTC) is similar to Greenwich Mean Time (GMT) but, unlike the latter, does not adjust to account for Daylight Savings Time. You can figure out which time zone you're in by searching Time Zone Map or Time Zone [CITY] UTC.

Prior to 1972, this time was called Greenwich Mean Time (GMT) but is now referred to as Coordinated Universal Time or Universal Time Coordinated (UTC). It is a coordinated time scale, maintained by the Bureau International des Poids et Mesures (BIPM). It is also known as "Z time" or "Zulu Time".

From east to west, they are: Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaiian-Aleutian Standard Time (HST), Samoa Standard Time, and Chamorro Standard Time.
