What does UTC stand for?

UTC stands for Coordinated Universal Time. The abbreviation is a compromise between the English “CUT” and the French “TUC” (Temps Universel Coordonné), chosen as a language-neutral form that neither English nor French speakers would claim as their own abbreviation.

Is UTC the same as GMT?

UTC and GMT display the same hours and minutes for most practical purposes. The difference is technical: GMT is based on the Earth’s rotation relative to the sun, while UTC is based on atomic clocks. UTC is the modern scientific standard; GMT is still widely used in everyday speech.

Why should I use UTC for scheduling international meetings?

UTC never observes daylight saving time, so it is always UTC+0 regardless of the season. This makes it unambiguous year-round. Stating a meeting time in UTC alongside local times for each participant eliminates the confusion that DST transitions can cause.
