What timezone does Sydney use?

Sydney observes Australian Eastern Standard Time (AEST, UTC+10) in winter and Australian Eastern Daylight Time (AEDT, UTC+11) in summer. Clocks go forward one hour in October and back in April, following the Southern Hemisphere calendar.

Is this clock accurate?

The clock reads your device's system clock and converts it to Australia/Sydney time using the IANA timezone database built into your browser. Accuracy depends on your device being synchronized via NTP, which most devices do automatically.

Does this account for Daylight Saving Time?

Yes. Modern browsers include the full IANA timezone database, which handles all past and future DST transitions for Australia/Sydney automatically.

When do the clocks change in Sydney?

Sydney clocks go forward one hour (AEST to AEDT) on the first Sunday in October at 2:00 AM, and go back one hour (AEDT to AEST) on the first Sunday in April at 3:00 AM.

What is the difference between AEST and AEDT?

AEST (Australian Eastern Standard Time) is UTC+10 and is observed from April to October. AEDT (Australian Eastern Daylight Time) is UTC+11 and is observed from October to April. The tool always shows the correct abbreviation and offset for today.
