What CST and CET Actually Are
CST — Central Standard Time
Chicago, Houston, Dallas, Mexico City, Winnipeg. Standing at UTC-6:00 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, November 1, 2026, to CST. CST also stands for China Standard Time (UTC+8) and Cuba Standard Time (UTC-5). This page covers the North American one.
Saskatchewan sits inside the Central zone but never changes its clocks, so it matches CST in winter and its neighbors' MDT in summer.
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.
What This Means in Practice
Both sides change clocks, on different dates
Both regions observe daylight saving but do not switch on the same day, so for a week or two each spring and fall the gap between them is an hour different from the rest of the year. Those short windows are where recurring invitations quietly break.
