Strange things happen when you travel, because the earth is divided into twenty-four zones (区). The time difference between two zones is one hour. You can have days with more than twenty-four hours and days with fewer than twenty-four hours. You can have weeks with more than seven days and weeks with fewer than seven days.

If you make a five-day trip across the Atlantic Ocean (大西洋),your ship comes into a different

time zone（时区） every day. As you come into each zone, the time changes one hour. If you travel west, you set your watch back. If you travel east, you set it ahead. Each day of your trip has either twenty-four or twenty-three hours.

If you make a trip by ship across the Pacific Ocean (太平洋) ,you cross the International Date Line

(国际日期变更线). This is point where a new day begins. When you cross the line, you change one full day. If you travel east, today becomes yesterday. If you travel west it is tomorrow.
