GMT to UTC: GMT is the same time as UTC
Greenwich Mean Time is the same time as Coordinated Universal Time, on every day of the year. It is 9:59 pm GMT in GMT and 9:59 pm UTC in UTC.
Convert a specific time from GMT to UTC
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between GMT and UTC?
Coordinated Universal Time is the same time as Greenwich Mean Time. To go from GMT to UTC you change nothing at all, because the two read the same clock. That gap holds on all 365 days of 2026: neither zone moves its clocks.
GMT to UTC conversion table
Every hour of Wednesday, September 23, 2026 in GMT, with the matching reading in UTC. No hour of the day crosses a date boundary between these two zones, so the calendar date is the same on both sides throughout.

What are the best hours to schedule a call between GMT and UTC?
8 hours of the standard 9:00 am to 5:00 pm working day line up in both zones, from 9:00 am GMT to 5:00 pm GMT. In UTC that window reads 9:00 am to 5:00 pm. Outside it, one side is either not yet at their desk or already gone.
| GMT | UTC | Working hours | Note |
|---|---|---|---|
| 9:00 am | 9:00 am | both sides | mid morning in GMT, mid morning in UTC |
| 10:00 am | 10:00 am | both sides | mid morning in GMT, mid morning in UTC |
| 11:00 am | 11:00 am | both sides | mid morning in GMT, mid morning in UTC |
| 12:00 pm | 12:00 pm | both sides | noon in GMT, noon in UTC |
| 1:00 pm | 1:00 pm | both sides | afternoon in GMT, afternoon in UTC |
| 2:00 pm | 2:00 pm | both sides | afternoon in GMT, afternoon in UTC |

Does daylight saving change GMT to UTC?
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.
Is GMT ahead of or behind UTC?
Neither. GMT and UTC read the same clock all year. Neither Greenwich Mean Time nor Coordinated Universal Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
Greenwich Mean Time covers identical to UTC as a clock reading, and a separate thing as a standard. Coordinated Universal Time covers the reference all other zones are measured against. The identifiers behind them are Etc/GMT and Etc/UTC, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
