4pm EST is 9:00 pm BST
4pm EDT is 9:00 pm BST in UK Time. BST is 5 hours ahead of EST today, and that gap changes during the year, so this is recomputed rather than assumed.
What time is 4pm EST in BST?
It is 9:00 pm. UK is 5 hours ahead of Eastern, so you add 5 hours to 4:00 pm and the date does not change. 4pm is afternoon in Eastern, the second half of the working day, while 9:00 pm is late evening in UK, the wind-down before midnight.
The 12 hour clock reuses every number twice, so 4pm and 4am differ only by the meridiem. Converting 4pm EST gives 9:00 pm BST; converting 4am EST gives 9:00 am BST. Losing the am or pm loses half the answer.
4pm EST to BST in the hours either side
The four hours before and after 4pm, in case the meeting moves. Note that the calendar date does not stay put across this window: it changes partway through, which is exactly where scheduling mistakes come from.

Is 4pm EST a good time to call BST?
No. 9:00 pm in UK is late evening, the wind-down before midnight. Nobody is taking that call. The zones are 5 hours apart, so the nearest sensible slot is a different hour entirely.
Does daylight saving change 4pm EST to BST?
Yes. Sampled at 4pm on every day of 2026, the gap takes 2 different values. Today it is 5 hours, which is why the answer above is dated rather than fixed.
Eastern Time is currently on EDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-4 to UTC-5.
UK Time is currently on BST and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+1 to UTC+0.
4pm BST to EST, the other way round
Running the question the other way is a different conversion, not a mirror image, because the two zones can be in different daylight saving states on the same date. 4pm BST is 11:00 am EST, which is a different reading from the answer above, because the two directions are separate questions. One wrinkle worth knowing: EST and EDT are two names for the same zone, not two zones. Eastern Time reads EST in winter and EDT in summer. When somebody types "est to bst" they nearly always mean the zone rather than the literal winter offset, so this page resolves EST to America/New_York and BST to Europe/London and applies whichever offset is genuinely in force on the day.
