Scheduling between GMT and EST

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 GMT is 4:00 AM EST. Always write the city alongside the abbreviation in invites — several abbreviations (CST, IST, AST) are used by more than one region.
