UTC to GMT converter
GMT is the same time as UTC right now. Live clocks on both sides, a direct time input, the full 24-hour table with a permalink per hour, and the real daylight-saving state — computed from the IANA tz database on every request, never from a stored offset.
Convert an exact time type it — no sliders
Conversion runs in your browser against the same IANA rules the server uses, so it keeps working offline and nothing you type is sent anywhere.
Daylight saving right now
Greenwich Mean Time
Etc/GMT is currently on GMT (UTC+00:00).
no clock change scheduled — this zone is fixed at UTC+00:00
GMT is UTC+0 and never shifts. The UK observes GMT in winter only — in summer it is on BST (UTC+1), so "GMT" on a British invite dated in July usually means BST.
Coordinated Universal Time
UTC is on UTC (UTC+00:00).
no clock change scheduled — fixed at UTC+00:00
UTC is the reference clock every other offset is quoted against. It has no daylight saving and never shifts.
