What CET and BRT 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.
BRT — Brasília Time
São Paulo, Rio de Janeiro, Brasília, Salvador. Standing at UTC-3:00 as written, and the region does not change its clocks, so that offset holds all year. Brazil abolished daylight saving in 2019, so this offset no longer shifts in the southern summer.
Brazil ran daylight saving for decades before abolishing it in 2019, on the argument that changed electricity consumption patterns had erased the savings.
What This Means in Practice
This gap is not fixed
CET changes its clocks and BRT 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.
