AEST to EST Converter

Choose a date and a Sydney or Melbourne time to see the time in New York, Toronto or Miami. Both sides use daylight saving in opposite halves of the year, and the converter tracks each change.

What is the time difference between AEST and EST?

Sydney is 14 to 16 hours ahead of New York. Subtract the gap from a Sydney time and you usually land on the previous calendar day in the US.

Offsets in 2026 – 2027, from the IANA time zone data in your browser's engine

Eastern Australia and the eastern United States sit in opposite hemispheres, so their summers fall in different months. New South Wales moves its clocks forward on the first Sunday in October and back on the first Sunday in April, as the NSW Government lists. The US moves forward on the second Sunday in March and back on the first Sunday in November.

Those four dates never line up, which is why the gap passes through 15 hours twice: once from mid-March to early April, when both sides are on daylight time, and again from early October to early November.

One column for each combination of clocks this year. −1 marks a time on the day before in New York.

Planning across the date line

Do

  • Write the weekday on both sides, for example Tue 8:00 AM AEDT / Mon 4:00 PM EST.
  • Move recurring calls in March, April, October and November, when one side changes its clocks.

Avoid

  • Using Brisbane time for Sydney in summer. Queensland stays on AEST and is an hour behind then.
  • Booking a Friday afternoon in New York for a Sydney team. It is already Saturday morning there.

The handiest overlap is early morning in Sydney, which matches the late afternoon of the day before in New York. A 7:30 AM start in Sydney during the southern summer is 3:30 PM in New York, enough time for a short call before the US office closes.

Live clocks for Sydney and Toronto show both cities now, and the EST to AEST converter runs the same math from the US side.

AEST to EST questions

How many hours ahead is Sydney of New York?

Between 14 and 16 hours. It is 14 hours from early April to early October, 16 hours from early November to mid-March, and 15 hours in the short stretches between those dates.

If it is 9:00 AM Monday in Sydney, what time is it in New York?

It is Sunday evening in New York: 5:00 PM when the gap is 16 hours, 6:00 PM at 15 hours and 7:00 PM at 14 hours.

Does Brisbane use the same time as Sydney?

Only in the Australian winter. Queensland stays on AEST (UTC+10) all year, so from October to April Brisbane is one hour behind Sydney.

What is the difference between AEST and AEDT?

AEST is UTC+10, the standard time in eastern Australia. AEDT is UTC+11, the daylight-saving time New South Wales, Victoria, the ACT and Tasmania use from October to April.

What is the best time for a Sydney–New York call?

Early morning in Sydney matches late afternoon or early evening of the previous day in New York, which is the most common overlap for both offices.
