What time zone is observed in Hong Kong year-round?

Hong Kong Time is the time zone observed in Hong Kong year-round.

Hong Kong uses UTC+08:00, eight hours ahead of Coordinated Universal Time. The Hong Kong Observatory serves as the territory’s official timekeeper, and the IANA time-zone identifier is Asia/Hong_Kong.

Hong Kong once used daylight saving time. The practice began in 1941, but it became unpopular and was permanently discontinued after 1979. As a result, clocks do not move forward seasonally today.

A common mix-up is treating Hong Kong Time as a separate offset from China Standard Time. Both use UTC+08:00, so Hong Kong’s clocks match mainland China’s clocks even though Hong Kong retains its own official name and legal definition for local time. Singapore and the Philippines also use UTC+08:00, but they are separate time-zone designations.
