Frequently Asked Questions

What does the EST to GMT converter do?
It converts Eastern Time (ET) to Greenwich Mean Time (GMT) so you can align schedules with global teams and GMT-based timelines.
Is GMT the same as UTC?
They are commonly treated the same for everyday scheduling, but technical systems typically prefer UTC. If precision matters, use UTC in documentation.
Why does the result change across the year?
Eastern Time switches between EST and EDT. If daylight saving is active on the date you pick, the offset to GMT changes.

Include the time zone label and the date, such as "Tue 2:00 PM ET = 7:00 PM GMT." This prevents confusion for international teams.
