UTM zones are numbered 1 through 60, starting at the international date line, longitude 180Â°, and proceeding east. Zone 1 extends from 180Â° W to 174Â° W and is centered on 177Â° W. Each zone is divided into horizontal bands spanning 8 degrees of latitude.
Time zones are based on the fact that the Earth moves 15 degrees longitude each hour. Since there are 24 hours in a day there are 24 standard time zones. (24 hours x 15Âº=360Âº). Time zones are counted from the Prime Meridian (0Âº longitude). Each time zone is counted at 15 Âº intervals and extends 7Â½Âº either side of a central meridian.
