BST vs EST
British Summer Time / UK (BST) is UTC+0 year-round. Eastern Time (US & Canada) (EST/EDT) is UTC−5 in winter and UTC−4 in summer.
The difference is a constant 5 hours behind — both zones switch to daylight saving on the same dates.

Scheduling between BST 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 BST 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.
