What CET and BDT 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.
BDT — Bangladesh Standard Time
Dhaka, Chattogram, Khulna. Standing at UTC+6:00 as written, and the region does not change its clocks, so that offset holds all year. Sometimes written BST, which collides with British Summer Time.
Bangladesh experimented with daylight saving for a single year in 2009 during a power crisis, then abandoned it.
What This Means in Practice
This gap is not fixed
CET changes its clocks and BDT 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 CET and BDT?
BDT is 4 hours ahead of CET. That is the live figure. Taken strictly as written, the gap between CET and BDT is 5 hours — the two differ because at least one of these regions is currently on daylight saving.

9:00 AM CET is 1:00 PM BDT.
What are the best hours to schedule a call between CET and BDT?
Between 9:00 AM and 1:00 PM CET, which is 1:00 PM to 5:00 PM BDT. Both sides are inside normal business hours through that window.
Does the difference between CET and BDT change during the year?
