ET to UTC Time Converter
UTC is 4 hours ahead of ET. The US East Coast is currently on EDT (UTC-4:00), and UTC is the zero point, UTC±00:00.
Best Time to Call Between ET and UTC
Both zones are inside normal business hours between 9:00 AM and 1:00 PM ET — that's 1:00 PM to 5:00 PM UTC. That's a 4-hour window.

What ET and UTC Actually Are
ET — Eastern Time
New York, Toronto, Washington DC, Atlanta, Miami, Boston. Standing at UTC-5:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to EST.
Eastern Time covers roughly half the US population and, because of that, is the zone most American business defaults to when nobody specifies one.
UTC — Coordinated Universal Time
The global reference standard. Aviation, computing and science run on it. Standing at UTC as written, and the region does not change its clocks, so that offset holds all year.
UTC is not a place. It is a computed standard, kept within a second of mean solar time at Greenwich by atomic clocks, and it is the reference every other zone is defined against.
What This Means in Practice
This gap is not fixed
ET changes its clocks and UTC does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.

Frequently Asked Questions
What is the time difference between ET and UTC?
UTC is 4 hours ahead of ET. That is the live figure. Taken strictly as written, the gap between ET and UTC is 5 hours — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM ET in UTC?
9:00 AM ET is 1:00 PM UTC.
What are the best hours to schedule a call between ET and UTC?
Between 9:00 AM and 1:00 PM ET, which is 1:00 PM to 5:00 PM UTC. Both sides are inside normal business hours through that window.
Does the difference between ET and UTC change during the year?
Yes. ET observes daylight saving and UTC does not, so the gap shifts by an hour at least twice a year. The next clock change is on Sunday, November 1, 2026.
