UTC → New York
8am UTC to EST
The answer
8am UTC is 04:00 in New York for most of the year, and 03:00 during the winter months — same day.
The two answers differ because the clocks change on one or both sides. Which one applies depends on the date, not on the hour.
Both halves of the year
| Period | UTC | New York | Day |
|---|---|---|---|
| Summer | 08:00 | 04:00 | same day |
| Winter | 08:00 | 03:00 | same day |
Daylight saving state
In summer, UTC is not on daylight saving time and New York is on daylight saving time. The next clock change in New York that moves this answer is 2026-11-01.
The hours either side
| UTC | New York (summer) | New York (winter) |
|---|---|---|
| 8am | 04:00 | 03:00 |
| 9am | 05:00 | 04:00 |
| 10am | 06:00 | 05:00 |
Going the other way
New York runs 4 hours behind of UTC, so to go back you reverse it. If you are writing this down for someone else, name the cities rather than the abbreviations — “UTC” and “EST” are only correct for part of the year, and some abbreviations mean different things in different countries. See EST vs EDT.
