See the live UTC time next to the current time in Sydney, check today's real offset, and roll through any UTC time to find the matching AEST/AEDT time — including when the two zones fall on different dates.

Coordinated Universal Time (UTC) is the world's time standard: it never shifts for seasons and every other zone is described as an offset from it. Australian Eastern Time (AEST/AEDT) is the clock used in Sydney. Converting UTC to AEST/AEDT means adding that offset to the UTC reading.
Australian Eastern Time covers New South Wales, Victoria, Queensland and Tasmania, though Queensland stays on AEST year round.
Take the UTC time, apply the current AEST/AEDT offset shown in the live panel above, and roll the date forward or back if the result crosses midnight. The interactive roller does all three steps for you: the left drum is UTC, the right drum is AEST/AEDT, and a day badge appears whenever the local date differs.
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.
The reference table below the tool lists every UTC half hour against the matching AEST/AEDT time for today, so you can copy a conversion without touching the roller.
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.
