What is the time difference between EST and AEST?
AEST is 15 hours ahead of EST. Both regions observe Daylight Saving Time, so the gap stays close to 15 hours year-round. 9:00 AM EST = 12:00 AM (next day) AEST. 12:00 PM EST = 3:00 AM (next day) AEST. 5:00 PM EST = 8:00 AM (next day) AEST.
What is the best time to call from New York to Sydney?
There is no 9-to-5 business hours overlap between EST and AEST. The typical compromise is early morning EST: 8:00 AM EST (11:00 PM AEST), or late evening EST: 6:00 PM EST (9:00 AM (next day) AEST). One side will be outside normal hours, so teams usually rotate who takes the off-hours call.
Frequently Asked Questions about EST and AEST
AEST is 15 hours ahead of EST, so to convert mentally, add 15 hours to your EST time. For example: 9:00 AM EST = 12:00 AM AEST (next day). Our converter automatically adjusts for Daylight Saving Time so you always get the right result.
AEST (Australian Eastern Standard Time, UTC+10) is 15 hours ahead of EST (Eastern Standard Time, UTC-5) during standard time. For example, 9:00 AM EST = 12:00 AM AEST (next day). During DST periods, this difference changes by 1 hour when one or both zones observe Daylight Saving Time - our converter automatically applies the correct offset for any date you select.
AEST is 15 hours ahead of EST, so standard 9–5 business hours do not overlap. The most practical window is early morning in EST (7–9 AM), which falls in the evening in AEST - for example, 7:00 AM EST = 10:00 PM AEST. Use our meeting planner to find the exact time for your date, especially around DST transitions.
Yes. EST (Eastern Standard Time) observes Daylight Saving Time. Clocks spring forward to EDT (UTC-4) on the second Sunday in March, and fall back to EST on the first Sunday in November. During the DST period, the difference with AEST changes by 1 hour. Our converter always uses the current offset for the date you select.
Major cities in the EST (Eastern Standard Time, UTC-5) timezone include: New York, Boston, Miami, Atlanta, Washington DC, Philadelphia, Toronto. These cities switch to EDT (UTC-4) from the second Sunday in March to the first Sunday in November.
Major cities in the AEST (Australian Eastern Standard Time, UTC+10) timezone include: Sydney, Melbourne, Canberra, Hobart (Brisbane uses AEST year-round without DST). These cities switch to AEDT (UTC+11) from the first Sunday in October to the first Sunday in April.
AEST is 15 hours ahead of EST. Because EST and AEST are 15 hours apart, there is no standard business-hour overlap - plan for one side to take an early morning or late evening call. Always include both local times in calendar invites (for example, "2:00 PM EST / 5:00 AM AEST (next day) AEST"). Double-check around March and November (or March/October for European zones) when DST transitions can shift the offset by 1 hour.
