The Earth is divided into 24 time zones. Why? Because there are 24 hours in a day!

6. Time Zones
Time zones are mostly drawn along lines of longitude, though some have been adjusted for convenience.
Each time zone is approximately 15° wide
When traveling west, you subtract hours (the time gets earlier)
When traveling east, you add hours (the time gets later)
