1pm GMT is 1:00 pm UTC
1pm GMT is 1:00 pm UTC in Coordinated Universal Time. That answer holds on every day of the year, because these two zones never drift apart.
What time is 1pm GMT in UTC?
It is 1:00 pm. GMT and UTC read the same clock, so the reading does not move at all. 1pm is afternoon in GMT, the second half of the working day, while 1:00 pm is afternoon in UTC, the second half of the working day.
Spoken as military time, 1pm is 1300 hours and the result is 1300 hours. The military convention exists precisely because "3 o'clock" is ambiguous twice over: once on the 12 hour clock and once across zones.
1pm GMT to UTC in the hours either side
The four hours before and after 1pm, in case the meeting moves. The whole window stays on the same day in UTC, so only the hour changes.
| GMT | UTC | UTC date | Working hours |
|---|---|---|---|
| 9:00 am | 9:00 am | same day | both sides |
| 10:00 am | 10:00 am | same day | both sides |
| 11:00 am | 11:00 am | same day | both sides |
| 12:00 pm | 12:00 pm | same day | both sides |
| 1:00 pm (this page) | 1:00 pm | same day | both sides |
| 2:00 pm | 2:00 pm | same day | both sides |
| 3:00 pm | 3:00 pm | same day | both sides |

Is 1pm GMT a good time to call UTC?
Yes. 1pm in GMT lands at 1:00 pm in UTC, which is inside the 9:00 am to 5:00 pm working day on both sides. It is afternoon for the caller and afternoon for the person picking up, so nobody is being asked for a favour.
Does daylight saving change 1pm GMT to UTC?
Not for this conversion. Sampled at 1pm on every day of 2026, the gap between these two zones comes out the same every single time, so 1pm GMT is 1:00 pm UTC in January and in July alike.
Greenwich Mean Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
Coordinated Universal Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
1pm UTC 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. 1pm UTC is 1:00 pm GMT, which is the same clock reading as the answer above. Neither Greenwich Mean Time nor Coordinated Universal Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
