Adelaide is in the Australian Central Standard Time timezone, commonly abbreviated as ACST.

Note that this offset changes during daylight saving time, when the abbreviation switches to ACDT.

Question 2

What is the UTC offset for Adelaide?

Accepted Answer

Adelaide has a UTC offset of UTC+10:30, which is based on the IANA timezone identifier Australia/Adelaide. During daylight saving time, the offset changes by one hour. This means Adelaide effectively operates at two different UTC offsets throughout the year, which is important to account for when scheduling international calls or meetings.

This typically happens in spring ("spring forward") and reverses in autumn ("fall back"). The transition can temporarily affect time differences with cities that do not observe DST or that switch on different dates. Check our DST change calendar for exact transition dates.
