About converting AEST to BST

Australian Eastern Time (Sydney) and British Time (London) (London) 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 AEST box (or tap a quick preset) and read the BST 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.

AEST vs BST: the time difference through the year

The gap between AEST and BST changes during the year because they switch to and from daylight saving on different dates.

Best time to meet

The two zones

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.

BST · British Time (London)

UK time is GMT (UTC+0) in winter and British Summer Time (BST, UTC+1) from the last Sunday in March to the last Sunday in October. Ireland and Portugal follow the same switch dates.

Frequently asked questions

6 answers
What is the time difference between AEST and BST?
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 Australian Eastern Time and British Time (London), so the time you see is always right for right now.
How do I convert AEST to BST?
Enter a time in the AEST box and the equivalent BST 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 AEST to BST converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind Sydney and London), which tracks daylight-saving changes automatically, so the current times and difference are correct.
What time is it in London right now?
The live clock above shows the current time in London (BST), updating every second, alongside AEST.
Does the AEST to BST time difference change?
Yes. Over the next 12 months it is 10 h behind or 11 h behind or 9 h behind, depending on the date — see the table of periods on this page.
What is a good meeting time for AEST and BST?
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.
