- •EDT is observed from the second Sunday of March to the first Sunday of November.
- •During EDT, the US East Coast is only 4 hours behind London (instead of 5).
- •Not all EST locations switch to EDT – Panama and Jamaica stay on EST year-round.

UTC+08:00Hong Kong Time (HKT, UTC+08:00) is the time zone for Hong Kong, 8 hours ahead of UTC.
- •Hong Kong does not observe daylight saving time and has kept UTC+08:00 since 1979.
- •HKT shares its offset with China Standard Time, Singapore Time and Philippine Time.
- •The Hong Kong Stock Exchange opens at 09:30 HKT.

EDT vs HKT: Offsets, DST and Best Call Times
EDT runs on Eastern Daylight Time (EDT) at UTC-04:00. HKT runs on Hong Kong Time (HKT) at UTC+08:00. That puts EDT 12 hours ahead of HKT — a difference of +12h at the current offsets.
In practice, when it is 9:00 AM in EDT it is 9:00 PM in HKT. Midnight in EDT is 12:00 PM in HKT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert EDT to HKT time
- Scheduling a call from EDT to HKT: a 10:00 AM start in EDT lands at 10:00 PM in HKT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +12h gap: EDT and HKT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in HKT is 9:00 PM in EDT.
- Watching a live event or market open: EDT viewers need 9:00 PM in HKT to catch a 9:00 AM start there, and 12:00 PM if the event is anchored to EDT.
- Always state the zone abbreviation, not just the hour. "3:00 PM EDT" is unambiguous; "3 PM" across a +12h gap is not.
- With a +12h gap there is no shared 9-to-5 window, so alternate the early start: one week EDT takes the early slot, the next week HKT does.
About EDT (Eastern Daylight Time)
Eastern Daylight Time (EDT) is used during the summer months (second Sunday of March to the first Sunday of November) in the Eastern Time Zone. During EDT, clocks are advanced by one hour to take advantage of longer daylight hours. Not all locations in the Eastern Time Zone observe DST – Panama, Jamaica, and most of the Caribbean remain on EST year-round.
About HKT (Hong Kong Time)
Hong Kong Time (HKT) is fixed at UTC+08:00 all year and does not observe daylight saving time. Hong Kong last used summer time in 1979 and has kept a single offset since. HKT shares the UTC+08:00 offset with China Standard Time, Singapore Time, Malaysian Time, Philippine Time and Australian Western Standard Time, but is listed separately because Hong Kong maintains its own timekeeping authority. As a major financial centre, Hong Kong's trading hours set the rhythm for markets across Asia, opening at 09:30 HKT which is 01:30 in London and 20:30 the previous evening in New York.
Best time to call between EDT and HKT
With a +12h offset there is no overlap inside a normal 9 AM – 5 PM day. HKT opens at 9:00 AM HKT, which is 9:00 PM in EDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
EDT and HKT have no shared working hours because of the +12h gap. Teams need to alternate early starts or rely on asynchronous handovers.
EDT is 12 hours ahead of HKT (EDT UTC-04:00 → HKT UTC+08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
