Earth is divided into 24 time zones. A time zone is a region with uniform standard time so areas near that location can keep the same time. Most time zones on land are offset by Coordinated Universal Time, or UTC, by a the whole hour (UTC-12 to UTC+14).
Meridian lines can be used to measure time zones. They split Earth into different time zones.
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
becase the sun or the moon is shining on that part of the earth
The earth is divided into 24 times zones. Divide 360 degrees by 24 and you will get the measure in degrees.
That is probably because we divide the day into 24 hours.
