Hong Kong to New York: time difference and meeting times
Everything you need to schedule between Hong Kong and New York — the current offset, both cities' daylight saving dates, and the hour-by-hour overlap of their working days.
Partial overlap only. There is no hour when both cities are inside core working hours. Both sides are awake and available at 00:00–01:00 UTC, 10:00–13:00 UTC, 22:00–00:00 UTC, but at least one of them is in the early morning or the evening. That is the realistic window for this pair.

Green rows are hours when both cities are inside core working hours (09:00–17:59 local). Amber rows are hours when both are awake but at least one is in the early morning or evening. Times shown are for 27 August 2026; the pattern shifts when either city changes its clocks.

Daylight saving
Hong Kong does not observe daylight saving — this offset is fixed all year. New York next moves its clocks back on 1 November 2026, to UTC−5.
Only one side changes its clocks
New York observes daylight saving and Hong Kong does not. The difference between these two cities is therefore not constant — it changes twice a year, entirely because of the New York side. A recurring meeting fixed to local time in Hong Kong will appear to move by an hour in New York, and vice versa.
These cities are usually on different calendar days
The gap here is large enough that for much of the day the two cities are not merely at different times but on different dates. When you agree a meeting, confirm the date in both cities explicitly — "Tuesday at 9" means two different moments depending on whose Tuesday you mean.
Scheduling across this corridor
East Asia and North America sit on opposite sides of the working day, and for most of these pairs the calendar date differs as well. A meeting that is late afternoon in the US lands the following morning in Tokyo or Seoul, which is usually the least painful arrangement: the Asian side takes it at the start of their day rather than the end of yours. Because Japan, Korea and China do not observe daylight saving, the entire seasonal shift comes from the North American side, so a slot fixed in local US time will drift by an hour twice a year while the Asian local time stays put.
About Hong Kong
Hong Kong holds a fixed offset year-round, eight hours ahead of UTC, sharing its clock with mainland China and Singapore. It last observed daylight saving in 1979. Its financial sector keeps unusually long hours, which widens the practical window at both ends beyond what the standard working day would imply.
About New York
New York is the reference clock for North American business scheduling — when a US company says "9am ET" without qualification, this is the zone they mean. It observes daylight saving from the second Sunday in March to the first Sunday in November, which is three weeks longer than the European season and the source of the annual transatlantic confusion. The working day starts early by European standards and calls before 9am local are common.
