What HKT and ET Actually Are
HKT — Hong Kong Time
Hong Kong and Macau. Standing at UTC+8:00 as written, and the region does not change its clocks, so that offset holds all year.
Hong Kong used summer time on and off until 1979, when it stopped for good. Proposals to bring it back have surfaced periodically and never carried.
ET — Eastern Time
New York, Toronto, Washington DC, Atlanta, Miami, Boston. Standing at UTC-5:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to EST.
Eastern Time covers roughly half the US population and, because of that, is the zone most American business defaults to when nobody specifies one.
What This Means in Practice
The date changes mid-working-day
For 3 of the eight hours in a normal HKT working day, the equivalent ET time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.
This gap is not fixed
ET changes its clocks and HKT does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.
Nearly opposite sides of the clock
At 12 hours apart, one side's morning is the other side's night. Handing work over at the end of a shift usually beats trying to get both parties in the same call.

Frequently Asked Questions
What is the time difference between HKT and ET?
ET is 12 hours behind HKT. That is the live figure. Taken strictly as written, the gap between HKT and ET is 13 hours — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM HKT in ET?
9:00 AM HKT is 9:00 PM the previous day ET.
What are the best hours to schedule a call between HKT and ET?
Standard business hours in these two zones do not overlap at all, so one side has to work outside the 9-to-5. The most workable window is 7:00 AM to 10:00 AM HKT, which is 7:00 PM to 10:00 PM ET.
Does the difference between HKT and ET change during the year?
Yes. ET observes daylight saving and HKT does not, so the gap shifts by an hour at least twice a year. The next clock change is on Sunday, November 1, 2026.
