Eastern Time (EST) is 4 hours behind Coordinated Universal Time (UTC).

Here is every hour of the day in EST and the same moment in UTC.

The green rows are the hours when both zones are inside 9 AM to 5 PM. The row marked Now is the hour it is in Eastern Time right now.

A team split between ET and UTC is at work together for 4 hours a day.

Taking 9 AM to 5 PM on each clock as the working day, both zones are at work from 9:00 AM to 1:00 PM EST (1:00 PM to 5:00 PM UTC).

A team spread across two time zones has fewer chances to notice someone drifting away. TeamPredict reads public LinkedIn signals to flag resignation risk early, wherever people work.

The gap between EST and UTC moves between 4 hours and 5 hours during the year.

Coordinated Universal Time never changes its clocks, but the United States does, so the gap moves by an hour each time Eastern Time moves.

These are the clock changes of both zones in 2026 and 2027.

EST stands for Eastern Time and UTC for Coordinated Universal Time on this page.

Eastern Time is EST (UTC−5) in winter and EDT (UTC−4) in summer. People write EST all year, and this page does too; the clock reads EDT right now. It moves its clocks forward at 2:00 AM on the second Sunday in March and back at 2:00 AM on the first Sunday in November.

UTC is the world's reference time, the zero point every other zone is measured from, and it never changes with the seasons.
