Live times in New York and Vienna
The two cities side by side. The January column uses the winter offsets (New York UTC−05:00, Vienna UTC+01:00); the July column uses the summer offsets (New York UTC−04:00, Vienna UTC+02:00).

The world clock shows the current time in both cities live, and the individual city pages — time in New York and time in Vienna — explain each city's time zone, offsets and daylight saving in full.
The time difference between New York and Vienna
The difference is constant: Vienna is 6 hours ahead New York on every day of the year. That is the simplest case in time-zone work — the answer does not depend on the date, and a meeting set for 09:00 in New York is always 15:00 in Vienna. The reason the difference never changes is that both cities observe daylight saving and change their clocks on the same dates.
To convert a time, add the difference: 09:00 in New York is 15:00 in Vienna in January and 15:00 in July; 17:00 in New York — the end of the working day — is 23:00 in Vienna in January and 23:00 in July. To go the other way, subtract it: 09:00 in Vienna is 03:00 in New York in January. The time difference calculator does the arithmetic for any date, and the UTC to Vienna page gives the full conversion table for Vienna.
Meeting overlap between New York and Vienna
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 Vienna.
January
| New York time | Vienna time | Both working? |
|---|---|---|
| 09:00 | 15:00 | Yes |
| 10:00 | 16:00 | Yes |
| 11:00 | 17:00 | Yes |
| 12:00 | 18:00 | Yes |
| 13:00 | 19:00 | Yes |
| 14:00 | 20:00 | Yes |
| 15:00 | 21:00 | Yes |
| 16:00 | 22:00 | Yes |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 New York time. 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 Vienna
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.
Vienna observes daylight saving: in 2026 the clocks go forward on 29 March 2026 and back on 25 October 2026, moving the offset from UTC+01:00 to UTC+02:00.
The difference changes on Sunday, 8 March 2026 and Sunday, 29 March 2026 and Sunday, 25 October 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 Vienna DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in New York (15:00–23:00 in Vienna). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
Calling and travel notes
When it is 09:00 in New York it is 15:00 in Vienna in January; when it is 12:00 in New York it is 18:00 in Vienna; when it is 17:00 in New York it is 23:00 in Vienna. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling between the Americas and Europe is the easiest intercontinental case: the difference is 5–9 hours, so the working days overlap for several hours. The best window is late morning in New York and afternoon in Vienna (or the reverse), when both sides are in their working day. Watch the three weeks in March when the United States has changed its clocks and Europe has not — the overlap shifts by an hour, and standing meetings land at the wrong time.

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 Vienna — explain each city's time zone, and the DST pages — New York DST 2026 and Vienna DST 2026 — give the exact change dates.
