About These Time Zones
GMT — Greenwich Mean Time (UTC) (UTC+0, all year) covers the global UTC reference.
EST — Eastern Time (UTC−5 standard, UTC−4 in summer) covers New York, Toronto, Miami.
GMT never changes, but EST observes daylight saving (becoming EDT, UTC−4, in summer) — so the gap between them shifts by an hour twice a year. This page always shows the current, correct difference.
Scheduling Across GMT and EST
For calls and meetings, aim for the overlap of normal working hours in both zones — the conversion table above makes the window easy to spot. Morning on the western side of the pair usually meets afternoon on the eastern side.
