Time zone FAQ
How many time zones are there?
There are 38 distinct UTC offsets in use, from UTC−12 to UTC+14, and several hundred IANA time zone regions. This page lists the 62 abbreviations that English-speaking searchers actually use.
Why do some abbreviations mean two things?
CST is both US Central Standard Time and China Standard Time; IST is India, Irish and Israel Standard Time; BST is British Summer Time and Bangladesh Standard Time. Each zone page on this site says which meaning it uses.
What is the difference between a standard and a daylight abbreviation?
EST is the winter name and EDT the summer name of the same clocks. The generic name, ET, covers both. A correct converter uses whichever one is in force on the date you pick.
What is UTC?
Coordinated Universal Time is the world's time standard and never changes for daylight saving time. Every other zone is described as an offset from UTC, such as UTC−5 or UTC+5:30.
