In theory, there are 15 degrees of longitude in each time zone. However, for political and economic reasons, the boundaries of some time zones have been extended or contracted. So, for example, the Eastern Time Zone in the US extends further west than it "should" in theory and is wider than 15 degrees.
There are 15 degrees of longitude in each standard time zone
A polar view of the planet is roughly circular, that is, a total 360 degrees. There are about 24 hours in each day. Divide 360 by 24; the answer is 15, so there are 15 degrees of longitude in each time zone.
There are 24 time zones. Divide 360 degrees longitude by 24 and you get 15 degrees for each one-hour time zone.
Since the earth rotates 360 degrees in 24 hours, each 1-hour time zone extends (360/24) = 15 degrees in longitude.
If you define a time zone as one hour then a 24 hour day will have 24 time zones which each will equal 15 degrees. Therefore an 18 hour day will have 18 time zones of 20 degrees each. 24 x 15 degrees = 360 degrees 18 x 20 degrees = 360 degrees
There are fifteen (15) degrees of longitude per time zone. (15 degrees x 24 zones = 360 degrees around the planet)
Time zones are ideally 15 degrees in width, so that 24 will cover the entire 360 degrees (180 east and 180 west)
There is only one official start, and that is the Greenwich Mean Time, measured at 0 degrees longitude. From the each time zone is equally divided by 15 degrees, both going East and West.
The time difference per degree is 4 minutes. (1440 minutes divided by 360). There are 15 degrees of longitude for each hourly time zone, yielding 24 zones times 15 degrees, which also equals 360.
There are 24 time zones. The Earth is 360 degrees around the circumference. So, for every 15 degrees of longitude there is one time zone.
There is no such longitude. The maximum degrees for lines of longitude is 180 east and west only.
A time belt, or zone, is 15 degrees of longitude wide.
