Accepted Answer

Question 2

What is the UTC offset for Sydney?

Accepted Answer

Sydney has a UTC offset of UTC+11, which is based on the IANA timezone identifier Australia/Sydney. During daylight saving time, the offset changes by one hour. This means Sydney effectively operates at two different UTC offsets throughout the year, which is important to account for when scheduling international calls or meetings.

Yes, Sydney observes daylight saving time. During DST, clocks move forward by one hour and the timezone abbreviation changes from AEST to AEDT. 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.
