Calling Hong Kong Long Distance
As a Special Administrative Region of China, Hong Kong adheres to China’s universal time, China Time. Like China, Hong Kong does not participate in Daylight Saving Time so its time difference from much of the U.S. and Europe changes over the year. Hong Kong is 8 hours ahead of Greenwich Mean Time and 13 hours ahead of Eastern Standard Time in the United States. However, during Daylight Saving Time in the U.S., Hong Kong is only 12 hours ahead of the eastern U.S.
Hong Kong does have its own country code, 852. Hong Kong does not have area codes; just dial the number you are trying to reach after dialing the country code. Nearly all subscriber numbers are 8 digits in the country. e.g. For an international call to Hong Kong dial 011-852-xxxx-xxxx.
