20*15 degrees=300 degrees wide
There are 24 time zones. Each is one hour wide.
The Earth is divided into 24 time zones, each approximately 15 degrees of longitude wide. This system creates the basis for standard time zones around the world.
Earth is divided into 24 standard time zones because there are 24 hours in a day. Each time zone represents a one-hour difference from the adjacent zones, with the prime meridian (0 degrees longitude) serving as the reference point for coordinating time worldwide.
Different time zones are the result of Earth's rotation and the need to coordinate time across regions. The Earth is divided into 24 time zones, each roughly 15 degrees of longitude wide, with the prime meridian serving as the reference point (GMT). Time zones help to synchronize activities and schedules across the globe.
Things do get hard to manage for some nations, especially those that straddle or are close to the International Date Line (which is in the middle of its time zone). There are no laws or rules telling other nations how to define their relationships to the time zones or to the date line. Even if there were, they would not be enforcible. The island nation of Kiribati, for example, took some extraordinary liberties in 1997 by declaring that the date line moves to the east, as far over as about 150 degrees W. The effect of this was to make Caroline Island, nearly 30 degrees east of the standard location of the date line, the first place to experience sunrise in the new millennium. Coincidence, do you think? Their 'moving' of the date line did not change times in the time zones; only the date line moved. _____________ According to the standard definitions of the time zones, there are 15 degrees of longitude in each one. Fifteen times 24 equals 360 degrees for a full circle.

Ideally, there would be 25 time zones ranging from UTC-12 to UTC+12 with each one a multiple of an hour offset from UTC and each covering 15° of longitude with the exception of 7.5° each for UTC+12 and UTC-12 (15° of longitude with the international date line going down the middle). However there are currently 40 time zones in use today, including UTC-3.5, UTC+5.5, UTC+8:45, UTC+12:45, UTC+14, etc. Some cover far more than 15° of longitude, most notably, China Standard Time, the one time zone used in the entire nation of China.
A time zone is determined by knowing that in theory, each standard time zone should be exactly 15 degrees wide. Also, i would like to send a hi to my calss of period 3 in mr.cappacio 2012-2013. It's me you guys bhu bye.
The earth is divided into 40 formal time zones, not 24 as might commonly be expected. See: http://en.wikipedia.org/wiki/List_of_time_zones for a complete list. Note that the number of time zones also varies with the season as some regions adopt daylight savings time (DST) while others (in the same time zone) choose not to use DST. This can lead to a seasonal increase or decrease in the total number of time zones. According to PHC there are 24 Major time zones
Different time zones are the result of the Earth's rotation and the need to coordinate timekeeping across regions that experience sunlight at different times. The Earth is divided into 24 time zones, each roughly 15 degrees of longitude wide, with boundaries determined to synchronize activities across the globe.
One would think the answer is 24. But no. There are a total of 55 about time zones in the world. Why so many? Each country decides their specific time. Most will adhere to a regional time zone, bit many will countries and regions that have their own time zones that are off by 30 minutes from the time zone around them such as Newfoundland, Venezuela, India, and Iran. Some are off by 15 minutes such as Nepal. In the Pacific several islands have their own time zones. They will share the same time as a neighboring island, but they are one calendar day ahead or behind their neighbors.
The United Kingdom has only one time zone in their area. This time zone is called the Greenwich Mean Time, this is because the United Kingdom is smaller than other areas and does not need different time zones for the amount of land that it is made up of.
The Uttermost Company's clocks cover all time zones. They offer a wide variety of both wall and table clocks.
