AEST to EST

About AEST to EST

This page converts Australian Eastern Time (AEST) to Eastern Time (ET). Pick a date and time, and the answer appears at once. Below it, a table shows every hour of that day.

ET is 16 hours behind Sydney from early November to early March, 14 hours from early April to early October, and 15 hours in the weeks between, because the two sides change their clocks at opposite times of the year. For example, 9:00 AM Sydney time is 5:00 PM EST (previous day) from early November to early March, 7:00 PM EDT (previous day) from early April to early October, and 6:00 PM EDT (previous day) in the weeks between.

Sydney time (AEST, or AEDT in summer) is used in Sydney, Melbourne, Canberra and Hobart. ET is the time in New York, Washington DC, Miami, Atlanta, Boston and Toronto.

The converter uses your browser's own time zone data, so daylight saving is handled for you — always right for the date you pick, in the past or the future.

AEST to EST time table

The difference changes three times a year, so the table has three columns. The middle one is for the few weeks when both sides are on daylight saving time (March to early April, and October). For one exact date, use the live table above.

A 9:00 AM to 5:00 PM working day in Sydney is 5:00 PM (previous day) to 1:00 AM ET from early November to early March, 6:00 PM (previous day) to 2:00 AM ET in the weeks between and 7:00 PM (previous day) to 3:00 AM ET from early April to early October.

Daylight saving time

Sydney uses AEST (UTC+10) in its winter and AEDT (UTC+11) in its summer — the opposite months to the US and Europe. The clocks go forward on the first Sunday of October and back on the first Sunday of April: daylight saving runs from October 4, 2026 to April 4, 2027, and from October 3, 2027 to April 2, 2028. Brisbane (Queensland) does not change its clocks: it stays on AEST all year.

Eastern Time uses EST (UTC−5) in winter and EDT (UTC−4) in summer. The US clocks go forward on the second Sunday of March and back on the first Sunday of November: March 8, 2026 to November 1, 2026, and March 14, 2027 to November 7, 2027.

Because the two sides change at opposite times of the year, the gap has three sizes. In 2026: 16 hours until March 8, 2026, 15 hours until April 5, 2026, 14 hours until October 4, 2026, 15 hours again until November 1, 2026, and 16 hours for the rest of the year. The live converter above always uses the right one for the date you pick.

Good to know

• EST or ET? Strictly, EST is only the winter time of the US East Coast; in summer it is EDT. Many people say "EST" all year when they mean "East Coast time". This page uses the real clock time for the date you pick, so the answer is right either way.
• Sydney is ahead. Sydney's morning is the US East Coast's afternoon or evening of the day before — check the day, not only the hour.
• Not all of eastern Australia changes. Sydney, Melbourne, Canberra and Hobart use daylight saving; Brisbane stays on AEST all year. For Brisbane, add it as a city in the converter.
• Planning a meeting? Pick the date and time, then add the other cities of the people you meet with. Everyone's time shows in one list.
• The answer comes from your device's time zone data. Nothing is sent anywhere.
