This UTC to GMT converter turns any time in Coordinated Universal Time (UTC) into Greenwich Mean Time (GMT), using your device clock so daylight saving is applied automatically. GMT and UTC show the same time. UTC is UTC+0; GMT is UTC+0.
UTC covers Reykjavik (same clock), servers and aviation; GMT covers Accra, Dakar, London in winter. Neither zone observes daylight saving time, so the difference is the same every day of the year.

Frequently asked questions
What is the time difference between UTC and GMT?
GMT and UTC show the same time. That comes from the UTC offsets: UTC is UTC+0 and GMT is UTC+0. For example, 9 am UTC = 9 am GMT.
Is GMT ahead of or behind UTC?
Neither. UTC and GMT share the same clock time all year. UTC is a time standard, not a zone with DST, which is why GMT and UTC read the same even though GMT is strictly a zone name.
Does UTC or GMT observe daylight saving time in 2026?
No. Neither UTC nor GMT changes its clocks, so the 0 hours difference holds every day of the year. That makes recurring meetings between Reykjavik (same clock) and Accra easy to keep at a fixed local time on both ends.
What is the best time for a meeting between UTC and GMT?
Standard office hours (9 am to 5 pm) overlap from 9 am to 5 pm UTC, which is 9 am to 5 pm GMT. Pick a slot inside that window and both sides stay within a normal working day. Check the daylight saving dates above, because the window moves by an hour when only one side has changed clocks.
Which cities use UTC and GMT?
UTC (Coordinated Universal Time) is used in Reykjavik (same clock), servers and aviation. GMT (Greenwich Mean Time) is used in Accra, Dakar, London in winter. Note that the United Kingdom is only on GMT in winter; from late March to late October London runs on British Summer Time, one hour ahead, so use the BST pages for UK business hours in summer.
