About HKT
A fixed, year-round offset.
Hong Kong Standard Time (HKT) is UTC+08:00, and Hong Kong has not used daylight saving time since 1979. Whether you're pulling a late night in Kowloon or syncing with partners in Sydney, Singapore, or Taipei, the clock never changes.
IANA zones · the technical identifiers
The zone that resolve to HKT.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about HKT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- When did Hong Kong permanently adopt HKT at UTC+08:00?
- Hong Kong has used UTC+08:00 as its standard time since 1904, apart from wartime changes and the Japanese occupation (1941–45). Its last summer time ended on 21 October 1979, and it has stayed on UTC+08:00 all year since.
- Does HKT share its offset with other major business hubs?
- Yes — UTC+08:00 is also the standard time for Singapore, mainland China, Taiwan, the Philippines, and Perth, making Hong Kong a natural syncing anchor for almost the entire Asia–Pacific workday.
- Is there ever a short-notice shift to HKT?
- No. Hong Kong has been a single, fixed offset zone with zero transitions since the 1979 anchor, so scheduling tools can treat it as fully static year-round.
- What hour does HKT land when London hits 09:00 UTC?
- At 09:00 UTC it is 17:00 in Hong Kong, the end of the working day there. That is 09:00 in London in winter (GMT) and 10:00 in summer (BST).
- What hour does HKT land when New York hits 09:00 ET?
- When New York opens at 09:00 ET, it is already 22:00 in Hong Kong in winter (EST, UTC-05:00) and 21:00 in summer (EDT, UTC-04:00), a gap that makes same-day coordination require either late-night or early-morning effort on one side.
- What practical day-to-day tips help teams sync with HKT?
- Have London teams schedule calls before 12:00 UTC so Hong Kong colleagues join before 20:00 local time, and have New York teams start by 07:00 ET to clear same-day approvals before Asia logs off.
- Does HKT's alignment with China Standard Time create a hidden overlap?
- Because both use UTC+08:00 with zero DST, cross-border teams in Shenzhen, Shanghai, and Hong Kong share identical timestamps, eliminating clock errors in supply-chain and financial pipelines.
