11pm GMT is 7:00 pm EST
11pm GMT is 7:00 pm EDT in Eastern Time. EST is 4 hours behind GMT today, and that gap changes during the year, so this is recomputed rather than assumed.
What time is 11pm GMT in EST?
It is 7:00 pm. Eastern is 4 hours behind GMT, so you subtract 4 hours from 11:00 pm and the date does not change. 11pm is late evening in GMT, the wind-down before midnight, while 7:00 pm is evening in Eastern, dinner and the end of the working day.
ISO 8601 would write this instant as 2026-09-24 23:00Z, the same moment expressed with no zone opinion at all. Both 11pm GMT and 7:00 pm EST are local readings of that one instant, which is the only thing either clock is really describing.
11pm GMT to EST in the hours either side
The four hours before and after 11pm, 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 11pm GMT a good time to call EST?
Marginally. 7:00 pm in Eastern is outside the 9:00 am to 5:00 pm working day but still a civilised hour, dinner and the end of the working day. Reasonable for something brief, poor for anything that needs a full room.
Does daylight saving change 11pm GMT to EST?
Yes. Sampled at 11pm on every day of 2026, the gap takes 2 different values. Today it is 4 hours, which is why the answer above is dated rather than fixed.
Greenwich Mean Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
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.
11pm EST to GMT, 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. 11pm EST is 3:00 am GMT, the next day, 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 "gmt to est" they nearly always mean the zone rather than the literal winter offset, so this page resolves GMT to Etc/GMT and EST to America/New_York and applies whichever offset is genuinely in force on the day.
