Frequently asked questions
Does this table change for daylight saving?
No. The offsets attached to these abbreviations stay fixed. A city may switch to a differently named abbreviation. AEDT is a daylight-saving designation.
Should I put an abbreviation in a meeting invitation?
Use an IANA city time zone and a full date. Abbreviations are useful shorthand when everyone agrees on the meaning, but they do not carry the complete rules that a calendar needs for recurring events.
Why can the day change?
The difference is 960 minutes. Adding or subtracting that amount can move the destination time before midnight or beyond the end of the source day. The last column makes that change explicit.
