Turn a Australian Eastern Time reading into Coordinated Universal Time. The panels show both clocks live, and the roller lets you line up any AEST/AEDT time against its UTC equivalent.

THE CLOCKS ABOVE ALWAYS SHOW THE LIVE CURRENT TIME. THE ROLLER BELOW IS A LOOKUP TOOL — ROTATING IT NEVER CHANGES THEM.
AEST/AEDT is 10 hours ahead of UTC
ET is 4 hours behind UTC
Australia (Eastern) is 14 hours ahead of United States (Eastern)

Australian Eastern Time is the local clock in Sydney. Converting it to UTC removes the local offset so the time can be shared with anyone in the world without ambiguity — which is exactly why UTC is used for servers, aviation and international scheduling.
Australian Eastern Time covers New South Wales, Victoria, Queensland and Tasmania, though Queensland stays on AEST year round.
Subtract the current offset shown in the offset panel from the local AEST/AEDT time. If the result goes below 00:00, UTC is still on the previous date. Use the roller to read the pairing directly instead of doing the arithmetic.
Because AEST/AEDT observes daylight saving time, the gap to UTC is not fixed — every clock and table on this page is calculated live from the Australia/Sydney IANA database, so today's real offset is always what you see.
Early-morning or late-night local times frequently sit on a different UTC date. The converter labels every selection as SAME DAY, NEXT DAY or PREVIOUS DAY so a deadline written in UTC is never off by 24 hours.
Eastern Australia uses AEST (UTC +10:00) in winter and AEDT (UTC +11:00) from October to April — the southern-hemisphere seasons run opposite to Europe and North America.
