What CET and WIB 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.

WIB — Western Indonesian Time

Jakarta, Surabaya, Bandung, Medan. Standing at UTC+7:00 as written, and the region does not change its clocks, so that offset holds all year. Indonesia spans three zones: WIB (UTC+7), WITA (UTC+8) and WIT (UTC+9).

Indonesia spans three time zones. A long-running proposal to unify the country onto a single clock has repeatedly stalled.

What This Means in Practice

This gap is not fixed

CET changes its clocks and WIB 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.
