About converting GMT to AEST

Greenwich Mean Time (Greenwich) and Australian Eastern Time (Sydney) are in different time zones, so a meeting, call or stream that's convenient in one may be early or late in the other. The clocks above update live and account for daylight saving automatically, so the time difference you see is the real one for today — not a fixed number that goes stale twice a year.

To plan across the two, type a time into the GMT box (or tap a quick preset) and read the AEST equivalent, including a "next day" or "previous day" note when the conversion crosses midnight. For any other pair of zones or cities, use the full timezone converter.

GMT vs AEST: the time difference through the year

The gap between GMT and AEST changes during the year because only one of them uses daylight saving.

Best time to meet

The two zones

GMT · Greenwich Mean Time

Greenwich Mean Time is UTC+0 all year. It is the base for world time; the UK uses GMT only in winter and switches to BST in summer.

AEST · Australian Eastern Time

Sydney is on AEST (UTC+10) from April to October and on daylight-saving AEDT (UTC+11) from the first Sunday in October to the first Sunday in April. Queensland (Brisbane) stays on AEST all year.

Frequently asked questions

6 answers
What is the time difference between GMT and AEST?
It's shown live at the top of this page (and it can change with daylight saving). The converter uses the current, DST-aware difference between Greenwich Mean Time and Australian Eastern Time, so the time you see is always right for right now.
How do I convert GMT to AEST?
Enter a time in the GMT box and the equivalent AEST time appears instantly, adjusted for the current offset between the two zones — including a note if it lands on the previous or next day.
Is this GMT to AEST converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind Greenwich and Sydney), which tracks daylight-saving changes automatically, so the current times and difference are correct.
What time is it in Sydney right now?
The live clock above shows the current time in Sydney (AEST), updating every second, alongside GMT.
Does the GMT to AEST time difference change?
Yes. Over the next 12 months it is 11 h ahead or 10 h ahead, depending on the date — see the table of periods on this page.
What is a good meeting time for GMT and AEST?
Standard 9-to-5 office hours don't overlap; early morning in one zone and evening in the other is the usual compromise — see the table on this page.
