Comparing Time Zones: AEDT and BST
AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. BST runs on British Summer Time (BST) at UTC+01:00. That puts AEDT 10 hours behind BST — a difference of -10h at the current offsets.
In practice, when it is 9:00 AM in AEDT it is 11:00 PM in BST on the previous day. Midnight in AEDT is 2:00 PM in BST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AEDT to BST time
- Scheduling a call from AEDT to BST: a 10:00 AM start in AEDT lands at 12:00 AM in BST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -10h gap: AEDT and BST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in BST is 11:00 PM in AEDT.
- Keeping family and friends in sync: knowing that 8:00 PM in AEDT is 10:00 AM in BST makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEDT" is unambiguous; "3 PM" across a -10h gap is not.
- With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week AEDT takes the early slot, the next week BST does.
About AEDT (Australian Eastern Daylight Time)
Australian Eastern Daylight Time (AEDT) is the daylight saving period in south-eastern Australia, one hour ahead of Australian Eastern Standard Time (AEST, UTC+10:00). Because Australia is in the southern hemisphere, AEDT runs through the summer — from the first Sunday in October to the first Sunday in April — which is almost exactly the reverse of the European and North American schedules. New South Wales, Victoria, Tasmania and the Australian Capital Territory observe it; Queensland and the Northern Territory do not, so Brisbane stays on AEST year round while Sydney moves to AEDT. During AEDT, Sydney is 11 hours ahead of UTC and 16 hours ahead of New York.
About BST (British Summer Time)
British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.
Best time to call between AEDT and BST
With a -10h offset there is no overlap inside a normal 9 AM – 5 PM day. BST opens at 9:00 AM BST, which is 11:00 PM in AEDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
AEDT and BST have no shared working hours because of the -10h gap. Teams need to alternate early starts or rely on asynchronous handovers.
AEDT is 10 hours behind BST (AEDT UTC+11:00 → BST UTC+01:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
