Time zones are ideally 15 degrees in width, so that 24 will cover the entire 360 degrees (180 east and 180 west)
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.
If a day had 36 hours instead of 24, each time zone would cover 30 degrees of longitude instead of the current 15 degrees. This is because the Earth rotates 360 degrees in 24 hours, so with 36 hours in a day, each hour of difference would correspond to 30 degrees of longitude.
There are fifteen (15) degrees of longitude per time zone. (15 degrees x 24 zones = 360 degrees around the planet)
360 degrees / 24 timezones = 15 degrees per timezone
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 15 degrees of longitude in each standard time zone
One hour equals 15 degrees.
If a day had 36 hours instead of 24, each time zone would cover 30 degrees of longitude instead of the current 15 degrees. This is because the Earth rotates 360 degrees in 24 hours, so with 36 hours in a day, each hour of difference would correspond to 30 degrees of longitude.

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.
Greenwich Mean Time (GMT) is the time at the Prime Meridian (0 degrees longitude). Each degree of longitude corresponds to a time difference of 4 minutes. At 20 degrees east longitude, the time would be 20 degrees × 4 minutes = 80 minutes ahead of GMT. Therefore, if it is 12 noon at Greenwich, the time at 20 degrees longitude would be 1:20 PM.
There are 24 time zones. Divide 360 degrees longitude by 24 and you get 15 degrees for each one-hour time zone.
360° of longitude divided by 24 time zones gives 15° per time zone (average)
If it is 10 am at 45 degrees W longitude, it is 4 pm at 45 E longitude.
A time zone typically spans 15 degrees of longitude, as there are 24 hours in a day and 360 degrees of longitude around the Earth. This means each time zone covers four meridians, one for each hour.
