EST vs GMT
Eastern Time (US & Canada) (EST/EDT) is UTC−5 in winter and UTC−4 in summer. Greenwich Mean Time / UK (GMT/BST) is UTC+0 in winter and UTC+1 in summer.
The difference is a constant 5 hours ahead — both zones switch to daylight saving on the same dates.

Scheduling between EST and GMT
The working-day overlap is a few hours: morning in the zone that's behind matches afternoon in the zone that's ahead. For example, 9 AM EST is 2:00 PM GMT. Always write the city alongside the abbreviation in invites — several abbreviations (CST, IST, AST) are used by more than one region.
