What CET and ART Actually Are

CET — Central European Time

Paris, Berlin, Madrid, Rome, Amsterdam, Vienna, Warsaw, Stockholm. Standing at UTC+1:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to CET. Most of continental Europe moves to CEST (UTC+2) for the summer.

Central European Time spans a remarkable stretch of longitude — from Spain's Atlantic coast to Poland's eastern border — so solar noon in Madrid arrives nearly two hours later than in Warsaw.

ART — Argentina Time

Buenos Aires, Córdoba, Rosario. Standing at UTC-3:00 as written, and the region does not change its clocks, so that offset holds all year. Argentina does not observe daylight saving, so this offset is fixed year-round.

Argentina has changed its time zone rules more than a dozen times since 1930 and abandoned daylight saving in 2009.

What This Means in Practice

This gap is not fixed

CET changes its clocks and ART does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, October 25, 2026 unless someone resets it.
