Nautical time zones are each made up of 15 degrees. Terrestrial time zones, however vary from zone to zone and country to country.
There are 15 degrees of longitude in each standard time zone

360 degrees / 24 timezones = 15 degrees per timezone
24 hours = 360 degrees so each hour = 360/24 = 15 degrees. Then, 14 time zones (if they are each one hour apart) = 14*15 = 210 degrees.
Theoretically, there are 24 times zones to cover the earth. So each time zone is 1 hour of time difference and 15 degrees. (Divide 360 by 24). However, practically, some time zones are larger than others. The line that seperates time zones are not straight. For example you can travel in the Central Time Zone and cover all of Texas, Arkansas, Mississippi and Alabama before the time changes. I'm sure that is greater than 15 degrees of earth's rotation.

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 24 time zones. Divide 360 degrees longitude by 24 and you get 15 degrees for each one-hour time zone.
You can earn as many bachelor degrees as you have the time and money for, as long as you meet the graduation requirements of each.
Each time zone would be approximately 18 degrees wide, since the Earth has 360 degrees of longitude and is divided into 20 time zones.
