UTC to EST Converter

Wall Street and the Office Day in UTC

A common reason to convert UTC to EST is lining up a server, a log or a release with the US market day. Exchange hours are fixed in local time, so their UTC time is an hour earlier in summer:

The NYSE core session is 9:30 AM to 4:00 PM Eastern. A job scheduled for 14:30 UTC fires at the market open in winter but an hour after it in summer, which is why schedules for US hours belong in the New York time zone, not a fixed UTC time.

UTC to EST Conversion Table

Full 24-hour table. EST is UTC-5 and EDT is UTC-4 (second Sunday in March to first Sunday in November).

* Before 05:00 UTC on EST (04:00 on EDT) the Eastern time falls on the previous calendar day.

Places on UTC-5 All Year

New York is on UTC-5 only in winter. Several places use UTC-5 all year, and Panama and Cancún call it Eastern Standard Time. The offsets on two dates in 2027:

From March to November these places show the same clock as New York minus one hour. The clock on a Panama or Bogotá phone does not move in March, so a UTC conversion for them uses the UTC-5 column all year.

When New York Changes

Eastern Time moves forward at 2:00 AM on the second Sunday in March and back at 2:00 AM on the first Sunday in November. UTC does not move, so the offset changes: 15:00 UTC is 10:00 AM on EST and 11:00 AM on EDT. The next three years, from the time zone database (the 2027 daylight saving page has every region):

Converting a Timestamp in Code

# Python 3.9+
from datetime import datetime
from zoneinfo import ZoneInfo
datetime.fromisoformat("2026-01-20T15:00:00+00:00").astimezone(ZoneInfo("America/New_York"))

// JavaScript
new Date("2026-01-20T15:00:00Z").toLocaleString("en-US", { timeZone: "America/New_York" })

Both give the EST time shown above.
