About these time zones
BST. BST is UK summer time, UTC+1, from the last Sunday in March to the last Sunday in October. For the rest of the year the UK is on GMT, so this page follows London time whatever the date you pick.
EST. Eastern Time is EST (UTC-5) in winter and EDT (UTC-4) from the second Sunday in March to the first Sunday in November. It covers New York, Toronto, Miami and most of the US East Coast.
Overlap. Meetings starting between 2:00 PM and 4:00 PM BST land inside a 9 to 5 working day in both zones.
