EST to GMT converter

EST to GMT quick reference

EST or EDT, GMT or BST? Daylight saving explained

EST (UTC−5) is the winter name and EDT (UTC−4) the summer name. Most people write “EST” all year and mean whatever the clocks say in New York, so MeetETA reads EST as local Eastern time on the date you pick, and says so when that date is on EDT.

GMT (UTC+0) is UK winter time; from late March to late October the UK is on BST (UTC+1). People who say “GMT” for a London meeting usually mean UK time, so this page uses London time. If you mean GMT as a fixed UTC+0 all year, it is the same as UTC (and that is how the type-a-time box reads the word “GMT”; type “London” for UK time).

Right now New York is on EDT, UTC−4 and London is on BST, UTC+1 (the clocks at the top of the page always show the live values).

How the gap changes during the year

London is 5 hours ahead of New York for most of the year. For a few weeks it is 4 h, because the two sides change their clocks on different dates.

Working-day overlap, hour by hour

Each row is an hour in New York. Green means that side is inside a 9–5 working day. There is 3 h of shared 9–5 time; the easiest window is 7 AM–5 PM EST (12 PM–10 PM GMT).

Shows New York 5 AM to 10 PM. Times on the London side may fall on the next day.
