What EST and AEST mean here

EST (Eastern Standard Time, UTC−5) is the winter time in New York, Washington, Atlanta, Miami and Toronto. From March 8 to November 1, 2026 those places use EDT (Eastern Daylight Time, UTC−4) instead. Most people who write "EST" mean "Eastern Time, whatever the clocks say today", so this converter follows the clocks in New York and switches between EST and EDT on the right days.

AEST (Australian Eastern Standard Time, UTC+10) is the time in Sydney, Melbourne, Canberra and Brisbane during the southern winter. Sydney, Melbourne and Canberra switch to AEDT (UTC+11) in summer, which in 2026 means January 1 to April 5 and from October 4, 2026. Brisbane (Queensland) stays on AEST all year. This page follows Sydney.

Questions

What is the time difference between EST and AEST?

Australian Eastern Time is 15 hours ahead of Eastern Time from March 8 to April 5 and from October 4 to November 1, 14 hours ahead of Eastern Time from April 5 to October 4, and 16 hours ahead the rest of 2026.

What is 9 AM EST in AEST?

Until March 14, 2027, 9:00 AM EST is 1:00 AM AEDT, noon EST is 4:00 AM AEDT, and 5:00 PM EST is 9:00 AM AEDT.

When do working hours overlap?

Until March 14, 2027, their 9-to-5 workdays don't overlap. The closest fit is early morning or evening in Eastern Time: 8:00 AM there is 12:00 AM the next day in Australian Eastern Time, and 5:00 PM is 9:00 AM the next day.

Why does the gap change twice as much as I expect?

Australia's summer is the northern winter, so its clocks go forward around the time US and European clocks go back, and the other way around in spring. When both sides switch in opposite directions the gap changes by two hours over a few weeks.
