UTC to EST Converter
Convert Coordinated Universal Time (UTC) to US Eastern Time. Daylight saving is detected automatically, so you always get the right label — EST or EDT.
Times are interpreted as UTC, regardless of your device's own time zone.
How the conversion works
Eastern Time is not a single fixed offset. The United States observes daylight saving time, so the offset changes twice a year:
- Eastern Standard Time (EST) — UTC−5, roughly November to March
- Eastern Daylight Time (EDT) — UTC−4, roughly March to November
So:
Eastern Time = UTC + offset where offset = −5 (EST) or −4 (EDT)
Worked example. 12:00 UTC on 31 August 2026 falls inside daylight saving, so the offset is −4:
12:00 − 4h = 08:00 EDT
The same 12:00 UTC on 15 January 2026 falls outside daylight saving, so the offset is −5:
12:00 − 5h = 07:00 EST
Common UTC to Eastern conversions
| UTC time | In summer (EDT, UTC−4) | In winter (EST, UTC−5) |
|---|---|---|
| 00:00 | 20:00 (prev. day) | 19:00 (prev. day) |
| 04:00 | 00:00 | 23:00 (prev. day) |
| 08:00 | 04:00 | 03:00 |
| 12:00 | 08:00 | 07:00 |
| 16:00 | 12:00 | 11:00 |
| 20:00 | 16:00 | 15:00 |
| 23:00 | 19:00 | 18:00 |
Frequently asked questions
- Is EST the same as EDT?
- No. EST is Eastern Standard Time (UTC−5), used in winter, while EDT is Eastern Daylight Time (UTC−4), used during daylight saving. This converter detects which one applies to your date and labels the result accordingly.
- What is the current offset between UTC and Eastern Time?
- Eastern Time is UTC−5 during Eastern Standard Time and UTC−4 during Eastern Daylight Time. Daylight saving in the US runs from the second Sunday in March to the first Sunday in November.
- Is this converter free and private?
- Yes. It is completely free, requires no signup, and all calculations run locally in your browser. Nothing you enter is uploaded.
- Which cities use Eastern Time?
- New York, Toronto, Miami, Philadelphia, Boston, Atlanta, Washington D.C. and Detroit all observe Eastern Time. Note that not every location in the Eastern time zone observes daylight saving.
