There are 360° around the spherical surface of the Earth, marking degrees of angle. There are 24 hours in a solar day. So a time of one hour would see the Earth rotate through 15°. (360/24 = 15)
Time zones are not all created equal. The edges can move in or out to capture territory that needs to be the same time as the rest of a state or country. Each time zone is normally one hour's difference from the adjacent zone. Clocks a zone to the east would be one hour later, and clocks a zone to the west would be one hour earlier.
The initial program for standardizing time would have the whole world on Greenwich Mean Time. This would mean clocks at the opposite side of the earth (180°) would show midnight when the Sun was at noon in Greenwich (0°).
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 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.
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 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.

the earth is divided into 24 time zones, each 15 degrees of longitude in width. Since earth rotates once every 24 hours on its axis and there are 360 degrees of , each hour of Earth rotation represents 15 degrees of longitude.
