London and Hong Kong Time Zone Comparison
London and Hong Kong are two major cities that sit in noticeably different time zones. London, the capital of the United Kingdom, is one of the world's leading financial centers, and much of global banking and stock-market activity is scheduled around London time. Hong Kong, a special administrative region of China, is one of the world's leading financial centers, and its stock exchange ranks among Asia's largest.
Because London and/or Hong Kong observe daylight saving time for part of the year, the gap between them isn't fixed — it ranges between 7 and 8 hours depending on the season.
With a gap this large, business hours barely overlap between London and Hong Kong — an early morning or a late evening on one side is usually needed to connect with the other.
