Frequently Asked Questions

What is the current UTC offset in Adelaide?
It is shown live in the offset panel above, derived from the Australia/Adelaide time zone rules for today's date.
Is Adelaide ahead of or behind UTC?
The offset panel states the direction and size of the difference in plain language, and updates automatically when daylight saving time starts or ends.
Why do some countries use 30-minute time zones?
A country picks the offset that best matches solar noon across its territory. Where a whole-hour offset would put the sun badly out of step — India, Iran, parts of Australia — a 30 or 45 minute offset fits better.
