About CET — Central European Time
Central European Time (CET) is UTC+1, the standard time for most of Central and Western Europe during winter months. It is one of the most widely used time zones in the world by number of countries, covering over 20 European nations. In summer, CET regions switch to Central European Summer Time (CEST, UTC+2) from the last Sunday in March to the last Sunday in October. CET is home to major European stock exchanges including Frankfurt (Deutsche Börse), Paris (Euronext), Amsterdam (Euronext), and Milan (Borsa Italiana).

About CET (CET)
CET (UTC+1) is a standard time zone designation used by Germany, France, Italy, and 14 other countries. Time zone abbreviations like CET refer to a specific UTC offset rather than a geographic region — multiple time zones around the world may share the same offset while using different local names.
When scheduling internationally, it is more reliable to refer to a city name or IANA time zone identifier (like America/New_York or Asia/Dubai) than to a short abbreviation, since abbreviations are not globally standardised and can be ambiguous — for example, CST refers to both Central Standard Time (UTC−6) in North America and China Standard Time (UTC+8).

UTC Offset vs IANA Time Zone: What's the Difference?
UTC Offset
A UTC offset like UTC+4 or UTC−5 is a simple number expressing how many hours and minutes a location is ahead of or behind Coordinated Universal Time. It is fixed and does not carry any information about DST rules or transitions.
IANA Time Zone
An IANA identifier like Europe/London or Asia/Tokyo is a database entry that includes the full history of UTC offset changes, DST rules, and historical exceptions for that location. IANA identifiers should always be preferred in software and scheduling systems.
