Understanding Time Zones Many people were disappointed that the 2000 Olympics in Sydney, Australia, were taped instead of broadcast live in the United States. Sydney, Australia, is 15 time zones away from the United States. At 7:00 PM in Sydney, it is 4:00 AM in New York City. Time differences have a strong impact on entertainment events, business activities, and on general communications. Consulting a time zone map can help to make allowances for time differences between various locations. THE LANGUAGE OF MAPS In this time zone map, eastern Russia and Alaska are

shown. The map displays eight time zones. Each zone is marked at the top of the map by a designated time. The International Date Line lies between the United States and Russia. This line marks the starting point of each day. When the International Date Line is crossed while traveling westward, the date is set forward to the next day. When traveling eastward across the line, the date is set back to the previous day. For example, if you are traveling westward on a ship and you cross the date line at noon on Sunday the date is set forward to noon on Monday.
