EDT vs BST — cities and working rhythm
US East Coast summer offset (mid-March to early November), UTC-4. The narrower gap to Europe (only 4 h during northern-hemisphere summer) means early-morning EU meetings align with reasonable East Coast times.
UK / Ireland summer offset (last Sunday of March to last Sunday of October) — UTC+1, same as CET. During BST, London aligns with continental European working hours rather than the standard 1-hour gap. Winter reverts to GMT (UTC+0).
Time gap: BST is 5.0 hours ahead of EDT (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
