CET vs UTC
Central European Time (CET/CEST) is UTC+1 in winter and UTC+2 in summer. Coordinated Universal Time (UTC) is UTC+0 year-round.
Because Central European Time observes daylight saving and the other zone does not, the gap changes during the year: 1 hour behind in the northern winter and 2 hours behind in summer, with a few weeks in spring and autumn where it's an hour different again. The converter uses the exact rules for the date you choose.

Scheduling between CET and UTC
With only 2 hours between them, normal working hours overlap most of the day — a call at 10 AM in Central European Time is 8:00 AM in Coordinated Universal Time. Always write the city alongside the abbreviation in invites — several abbreviations (CST, IST, AST) are used by more than one region.
