A team split between ET and GMT 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 GMT).
EST at work, 9 AM to 5 PM
GMT at work, 9 AM to 5 PM
Both at work: 4 hours
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 GMT moves between 4 hours and 5 hours during the year.
Greenwich Mean Time never changes its clocks, but the United States does, so the gap moves by an hour each time Eastern Time moves.

EST stands for Eastern Time and GMT for Greenwich Mean 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.
GMT is UTC+0 all year and never changes. London uses GMT only in winter and moves to BST (UTC+1) in summer.
These nearby time zone pairs show the time right now too.
The time zone converter reads one moment on up to 12 clocks, the military time converter turns 24-hour times into AM and PM, and the time duration calculator measures the hours between two moments.
Here are four questions about EST to GMT, answered.
- What is 9 AM EST in GMT?
- 9:00 AM EST is 1:00 PM GMT, and 5:00 PM EST is 9:00 PM GMT. From Sunday, November 1, 2026 the gap is 5 hours, so 9:00 AM EST is 2:00 PM GMT.
- What is the time difference between EST and GMT?
- Eastern Time (EST) is 4 hours behind Greenwich Mean Time (GMT). The gap between EST and GMT moves between 4 hours and 5 hours during the year. Greenwich Mean Time never changes its clocks, but the United States does, so the gap moves by an hour each time Eastern Time moves. After today, it becomes 5 hours on Sunday, November 1, 2026 and then 4 hours on Sunday, March 14, 2027.
- Is GMT the same as London time?
- Only in winter. GMT is UTC+0 all year, while London moves to BST (UTC+1) in summer. London's clocks move on these days. In 2026: Mar 29 and Oct 25. In 2027: Mar 28 and Oct 31. For a London meeting in summer, use the BST to EST page.
- What is a good time for a meeting between EST and GMT?
- 9:00 AM to 1:00 PM EST (1:00 PM to 5:00 PM GMT) is 4 hours when both sides are inside 9 AM to 5 PM, so a meeting there starts and ends in everyone's normal day.
