This EST to AEST converter turns any time in Eastern Standard Time (EST) into Australian Eastern Standard Time (AEST), using your device clock so daylight saving is applied automatically. AEST is 16 hours ahead of EST when both zones are on standard time, and 14 hours ahead during the summer months when clocks have shifted. EST is UTC−5 (EDT: UTC−4); AEST is UTC+10 (AEDT: UTC+11).
EST covers New York, Toronto, Miami; AEST covers Sydney, Melbourne, Canberra. 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 EST and AEST?
AEST is 16 hours ahead of EST on standard time. During daylight saving the gap changes to 14 hours. That comes from the UTC offsets: EST is UTC−5 and AEST is UTC+10. For example, 9 am EST = 1 am AEST the next day, and in summer 9 am EST = 11 pm AEST.
Is AEST ahead of or behind EST?
AEST is 16 hours ahead of EST, so when it is noon in EST it is 4 am in AEST the next day. Ahead means the clock there already shows a later time; a call at 5 pm EST lands at 9 am AEST.
Does EST or AEST observe daylight saving time in 2026?
EST switches to EDT (UTC−4) on March 8 and back on November 1 in 2026. AEST switches to AEDT (UTC+11) on April 5 and back on October 4. 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 EST and AEST?
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 EST = 12 am AEST the next day and 6 pm EST = 10 am AEST the next day. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use EST and AEST?
EST (Eastern Standard Time) is used in New York, Toronto, Miami, Atlanta. AEST (Australian Eastern Standard Time) is used in Sydney, Melbourne, Canberra, Brisbane (no DST). Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
