Common questions
What is UTC in GMT?
GMT is 1 hour ahead of UTC today: noon in UTC is 13:00 in GMT.
Is UTC the same all year?
UTC refers to the offset used by UTC. Where that zone observes daylight saving, the letters change with it, which is why this site stores the identifier and not the abbreviation.
When can UTC and GMT meet?
Working hours overlap for 8 hours a day: the shaded overlap is 10:00–18:00 in GMT (09:00–17:00 your time).
