UTC to EST converter

New York is UTC−5 in winter and UTC−4 in summer. UTC itself never moves, so twice a year the same UTC timestamp lands an hour differently on a New York clock.

Where UTC times turn up

Hardly anyone lives on UTC, but a great many systems do. If you are in the eastern US, most of the UTC times you meet come from software, flight plans and the internet, and each has its own trap.

Log files and ISO timestamps

A timestamp ending in Z or +00:00 is UTC.

  • 2026-12-02T14:30:00Z = 9:30 AM EST on 2 December
  • 2026-07-02T14:30:00Z = 10:30 AM EDT on 2 July
  • An error logged at 02:15Z on the 3rd happened at 9:15 PM on the 2nd in New York (winter)

The date is the part people miss. Anything between 00:00 and 05:00 UTC in winter belongs to the previous evening in New York.

Scheduled jobs set in UTC

Cloud schedulers and CI systems such as GitHub Actions read cron schedules in UTC.

  • A job at 0 5 * * * (05:00 UTC) runs at 12:00 AM in winter and 1:00 AM in summer
  • A 13:00 UTC report arrives at 8:00 AM EST or 9:00 AM EDT

If a job must run at 9 AM New York time all year, schedule it in the America/New_York zone, or add a second entry and switch it on the change dates.

Flying and weather: Zulu time

Pilots, air traffic control and aviation weather reports use UTC, written as Z or “Zulu”.

  • A METAR issued at 1851Z = 1:51 PM EST (2:51 PM EDT)
  • A departure filed for 2300Z = 6:00 PM EST

Zulu is the same all year, which is exactly why aviation uses it: nobody has to ask which side of a clock change a flight plan was written on.

Midnight-UTC resets

Plenty of online services roll over their day at 00:00 UTC.

  • Crypto exchanges close their daily candle at 00:00 UTC = 7:00 PM EST / 8:00 PM EDT
  • Coding sites and games with a daily challenge often reset at the same moment

For the eastern US that is an evening event, not a midnight one, and it moves an hour with the seasons.

UTC, GMT and Z are the same clock reading

UTC (Coordinated Universal Time) is the world’s reference time, kept by atomic clocks. GMT is a time zone that shows the same reading as UTC, which is why the two are used interchangeably. Z is shorthand for both. The practical difference is that the UK leaves GMT for summer time, while UTC never changes.

One trap for developers: in the time zone database the zone called Etc/GMT+5 means UTC−5, with the sign reversed. It is almost never what you want for New York anyway, because a fixed offset ignores daylight saving. Use America/New_York.

On the West Coast? Pacific Time is UTC−8 in winter and UTC−7 in summer, three hours behind New York all year. The same 14:30Z timestamp is 6:30 AM in Los Angeles in December and 7:30 AM in July, and a midnight-UTC reset lands at 4:00 PM (winter) or 5:00 PM (summer) the evening before. Use America/Los_Angeles in code.

Converting UTC to New York time in code

Store times in UTC and convert only when you display them, using the named zone rather than a hard-coded −5 or −4. In a browser or Node.js:

new Date('2026-12-02T14:30:00Z').toLocaleString('en-US', { timeZone: 'America/New_York' })

That returns 12/2/2026, 9:30 AM, and the same line gives the right answer in July without any change, because the zone rules know when New York is on EDT. Python’s zoneinfo.ZoneInfo('America/New_York') does the same job.

Every UTC hour in New York

Left column is UTC, then New York and Los Angeles. Read the winter columns (EST, PST) from early November to mid-March and the summer ones (EDT, PDT) the rest of the year. Highlighted rows fall inside the New York business day in both seasons.

“prev. day” marks UTC hours that are still the evening before in New York.

Quick answers

12:00 UTC is what time in New York?

7:00 AM in winter (EST) and 8:00 AM in summer (EDT).

How do I convert UTC to Eastern Time?

Subtract 5 hours from early November to mid-March, and 4 hours from mid-March to early November. If the result goes below midnight, the New York date is the day before.

What is 00:00 UTC in EST?

00:00 UTC is 7:00 PM EST on the previous day. In summer it is 8:00 PM EDT, also on the previous day.

Is UTC the same as GMT?

They show the same time, so for converting to New York you can treat them as equal. The difference is that UTC is a standard that never changes, while the UK leaves GMT for British Summer Time in summer.

What does the Z at the end of a timestamp mean?

Z stands for Zulu time, which is UTC. 14:30Z is 14:30 UTC, or 9:30 AM in New York during winter.

What is UTC in Pacific Time?

Subtract 8 hours in winter (PST, UTC−8) and 7 hours in summer (PDT, UTC−7). 12:00 UTC is 4:00 AM PST or 5:00 AM PDT.

Why does my UTC job run at a different New York time after the clocks change?

Because UTC stays put while New York moves. A job at 13:00 UTC runs at 9:00 AM in summer and 8:00 AM in winter on a New York clock.
