Time Zones

Time Zones • As you travel around the world, you either gain or lose time as you pass through different time zones • The Earth is divided into 24 time zones. Why? Because there are 24 hours in a day!

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)

Practice • If it is 2: 00 pm in TX, what time is it in CO? • 1: 00 pm • If it is 2: 00 pm in AZ, what time is it in FL? • 4: 00 pm

Time Zones • International Date Line – 180 o from the Prime Meridian • Crossing it either advances time one day or causes it to go back one day

Time Zones • Places east of the International Date Line are one day behind those that are west. • If you are traveling east, you subtract your calendar one day. • If you are traveling west, you add one day. Jan. 29 Jan. 28

Time Zones • Practice: • The flight from CA to Tokyo takes 11 hours. If you fly from CA at 8: 00 AM on July 2, what day would it be when you arrive in Tokyo? • July 3

Way to remember the time zones and the international date line • “We WANT to stay ahead, but it is EASY to fall behind. ” • The “W” stands for west and the “E” stands for east. Jan. 29 Jan. 28
