What COT and CET Actually Are
COT — Colombia Time
Bogotá, Medellín, Cali, Barranquilla. Standing at UTC-5:00 as written, and the region does not change its clocks, so that offset holds all year.
Colombia briefly tried daylight saving during the energy crisis of 1992-93 and has not repeated it.
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
This gap is not fixed
CET changes its clocks and COT 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.

Frequently Asked Questions
What is the time difference between COT and CET?
CET is 7 hours ahead of COT. That is the live figure. Taken strictly as written, the gap between COT and CET is 6 hours — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM COT in CET?
9:00 AM COT is 4:00 PM CET.
What are the best hours to schedule a call between COT and CET?
Between 9:00 AM and 10:00 AM COT, which is 4:00 PM to 5:00 PM CET. Both sides are inside normal business hours through that window.
