When it is 09:00 in New York it is 22:00 in Hong Kong in January and 21:00 in July. Hong Kong is 13 hours ahead New York right now — but it is not constant: the difference is 13 hours ahead in January and 12 hours ahead in July. This page gives the live times in both cities, the overlap between their working days, the daylight saving dates that move the difference, and the best meeting windows.

Live times in New York and Hong Kong
The two cities side by side. The January column uses the winter offsets (New York UTC−05:00, Hong Kong UTC+08:00); the July column uses the summer offsets (New York UTC−04:00, Hong Kong UTC+08:00).

The world clock shows the current time in both cities live, and the individual city pages — time in New York and time in Hong Kong — explain each city's time zone, offsets and daylight saving in full.
The time difference between New York and Hong Kong
The difference is not constant. In January Hong Kong is 13 hours ahead New York; in July it is 12 hours ahead New York. The difference changes on Sunday, 8 March 2026 (from 13 hours ahead to 12 hours ahead) and Sunday, 1 November 2026 (from 12 hours ahead to 13 hours ahead) — those are the dates when one of the two cities changes its clocks and the other does not, or when they change on different days. Between those dates the difference is one value; outside them it is the other.
To convert a time, add the difference: 09:00 in New York is 22:00 in Hong Kong in January and 21:00 in July; 17:00 in New York — the end of the working day — is 06:00 in Hong Kong in January and 05:00 in July. To go the other way, subtract it: 09:00 in Hong Kong is 20:00 in New York in January. The time difference calculator does the arithmetic for any date, and the UTC to Hong Kong page gives the full conversion table for Hong Kong.
Meeting overlap between New York and Hong Kong
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in New York's working day and shows what time they are in Hong Kong.
January
| New York time | Hong Kong time | Both working? |
|---|---|---|
| 09:00 | 22:00 | No |
| 10:00 | 23:00 | No |
| 11:00 | 00:00 | No |
| 12:00 | 01:00 | No |
| 13:00 | 02:00 | No |
| 14:00 | 03:00 | No |
| 15:00 | 04:00 | No |
| 16:00 | 05:00 | No |
July
| New York time | Hong Kong time | Both working? |
|---|---|---|
| 09:00 | 21:00 | Yes |
| 10:00 | 22:00 | Yes |
| 11:00 | 23:00 | Yes |
| 12:00 | 00:00 | Yes |
| 13:00 | 01:00 | Yes |
| 14:00 | 02:00 | Yes |
| 15:00 | 03:00 | Yes |
| 16:00 | 04:00 | Yes |
In January the overlap is 0 hours: there is no hour when both cities are in their working day. In July it is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 New York time. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in New York and Hong Kong
New York observes daylight saving: in 2026 the clocks go forward on 8 March 2026 and back on 1 November 2026, moving the offset from UTC−05:00 to UTC−04:00.
Hong Kong does not observe daylight saving, so its offset of UTC+08:00 never changes.
The difference changes on Sunday, 8 March 2026 and Sunday, 1 November 2026 in 2026. On those dates, one city changes its clocks and the other does not — or they change on different days — so the difference moves by an hour. A standing meeting set in one city's local time will land an hour early or late on the other side until the second city catches up. The fix is to set the calendar event in UTC, or to check the overlap again after each change. The individual DST pages — New York DST 2026 and Hong Kong DST 2026 — give the exact dates for each city.
Best meeting windows
In July the best windows are 09:00–17:00 in New York (21:00–05:00 in Hong Kong) — the same logic, with the July offsets.
Calling and travel notes
When it is 09:00 in New York it is 22:00 in Hong Kong in January; when it is 12:00 in New York it is 01:00 in Hong Kong; when it is 17:00 in New York it is 06:00 in Hong Kong. The difference is 12 hours or more, so the two cities are on different dates for part of the day: when it is Monday morning in New York, it is still Sunday in Hong Kong if Hong Kong is behind, or already Monday evening if it is ahead. Always state the date as well as the time when you schedule across this pair. Scheduling between the Americas and Asia is the hardest case in time-zone work: the difference is 12 hours or more, so one side's working day is the other's night. The only workable approach is to meet at the edge of the day — early morning in New York and evening in Hong Kong, or the reverse — and to keep the meeting short. Rotate the awkward hour week by week, or the same side will always be the one giving up its evening. Record the meeting and share notes, so the side that could not attend can still follow the decision.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in New York and time in Hong Kong — explain each city's time zone, and the DST pages — New York DST 2026 and Hong Kong DST 2026 — give the exact change dates.
