Hong Kong is located in the southern part of China, just south of the Tropic of Cancer. Hong Kong Island is 32km (20 miles) east of the mouth of Pearl River and 135km (84 miles) southeast of Canton. It is separated from the mainland by a good natural harbour. Hong Kong Island was ceded to Britain in 1842 by the Treaty of Nanking; and the Kowloon Peninsula (south of Boundary Street and Stonecutters Island) in 1860 by the Convention of Peking.
The area of Boundary Street to Shenzhen River and a group of 260 islands, now known as the New Territories, were leased to Britain in 1898 for a period of 99 years. The New Territories (plus the 260 islands) comprise 891 sq km (380 sq miles). Shortage of land suitable for development has led to reclamation from the sea, principally from the seafronts of Hong Kong Island and Kowloon.
The area of Hong Kong is 1097 sq km (423.6 sq miles). The time zone is GMT + 8. Hong Kong is 13 hours ahead of New York, 14 hours ahead of Chicago, and 16 hours ahead of Los Angeles. Since Hong Kong does not have a daylight saving time, subtract one hour from the above times if it's summer.
Because Hong Kong is on the other side of the international Date Line, you lose one day when traveling from the United States to America. Don't worry-you gain or back when you return to North America, which means that you arrive back home the same day you left Hong Kong.
