What CET and CDT 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.
CDT — Central Daylight Time
Chicago, Houston, Dallas, Winnipeg. Standing at UTC-5:00 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. Mexico abolished daylight saving in 2022, so Mexico City stays on UTC-6 all year and no longer uses CDT.
Mexico left this pattern behind in 2022, abolishing daylight saving nationwide except in a strip of cities along the US border that kept it for cross-frontier trade.
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.

Frequently Asked Questions
What is the time difference between CET and CDT?
CDT is 7 hours behind CET. That is the live figure. Taken strictly as written, the gap between CET and CDT is 6 hours — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM CET in CDT?
9:00 AM CET is 2:00 AM CDT.
What are the best hours to schedule a call between CET and CDT?
Between 4:00 PM and 5:00 PM CET, which is 9:00 AM to 10:00 AM CDT. Both sides are inside normal business hours through that window.
Does the difference between CET and CDT change during the year?
Yes. Both regions observe daylight saving, and they do not switch on the same dates, so the gap shifts by an hour at least twice a year. The next clock change is on Sunday, October 25, 2026.
Does CET always mean Central European Time?
Most of continental Europe moves to CEST (UTC+2) for the summer.
Does CDT always mean Central Daylight Time?
Mexico abolished daylight saving in 2022, so Mexico City stays on UTC-6 all year and no longer uses CDT.
