This AEST to EST converter turns any time in Australian Eastern Standard Time (AEST) into Eastern Standard Time (EST), using your device clock so daylight saving is applied automatically. EST is 16 hours behind AEST when both zones are on standard time, and 14 hours behind during the summer months when clocks have shifted. AEST is UTC+10 (AEDT: UTC+11); EST is UTC−5 (EDT: UTC−4).
AEST covers Sydney, Melbourne, Canberra; EST covers New York, Toronto, Miami. Because both zones change their clocks on different dates, the difference is not constant through the year. The tables below show both cases, and the converter at the top always uses the rule in force on the date you pick.

Frequently asked questions
What is the time difference between AEST and EST?
EST is 16 hours behind AEST on standard time. During daylight saving the gap changes to 14 hours. That comes from the UTC offsets: AEST is UTC+10 and EST is UTC−5. For example, 9 am AEST = 5 pm EST the previous day, and in summer 9 am AEST = 7 pm EST the previous day.
Is EST ahead of or behind AEST?
EST is 16 hours behind AEST, so when it is noon in AEST it is 8 pm in EST the previous day. Ahead means the clock there already shows a later time; a call at 5 pm AEST lands at 1 am EST.
Does AEST or EST observe daylight saving time in 2026?
AEST switches to AEDT (UTC+11) on April 5 and back on October 4 in 2026. EST switches to EDT (UTC−4) on March 8 and back on November 1. Between those dates the difference in the table above shifts by an hour, which is the usual cause of missed calls in spring and autumn.
What is the best time for a meeting between AEST and EST?
Office hours (9 am to 5 pm) do not overlap at all with a 16 hours difference. The least painful options are early morning in EST or early evening in AEST; for example 8 am AEST = 4 pm EST the previous day and 6 pm AEST = 2 am EST. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use AEST and EST?
AEST (Australian Eastern Standard Time) is used in Sydney, Melbourne, Canberra, Brisbane (no DST). EST (Eastern Standard Time) is used in New York, Toronto, Miami, Atlanta. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
