world+time+Zones

Time zones can be a little tricky. Here's a couple of tips:

1. Locate the starting city or country on the time zone map. You may need a world political map to find the cities and countries. 2. Add 1 hour for each zone you move to the east (right). 3. Subtract 1 hour for each zone you move to the west (left). 4. Go to the next day if you cross the International Date Line from east to west. 5. Go back a day if you cross the International Date Line from west to east.
