AEST vs EST — What You Need to Know

Australian Eastern Standard Time (AEST) is UTC+10. During Australian DST (October–April), NSW, VIC, ACT, and TAS observe AEDT (UTC+11). Queensland stays on AEST year-round.

US Eastern Standard Time (EST) is UTC-5 (EDT: UTC-4 from March to November).

The gap is 15h (AEST vs EST) to 16h (AEDT vs EST), making Australia–US East Coast one of the widest time zone gaps among major trading partners. The best window is 7:00–9:00 AM EST = 10:00 PM–12:00 AM AEST — requiring Australian participants to work into the late evening.

Note on DST shift:

Both regions observe DST but on opposite hemispheres: Australia (Oct–Apr) and the US (Mar–Nov). The gap is widest (16h) when Australia is in AEDT and the US is in EST simultaneously (November–March).

Frequently Asked Questions

How many hours ahead is AEST compared to US EST?

AEST (UTC+10) is 15 hours ahead of US EST (UTC-5). During Australian DST, AEDT (UTC+11) is 16 hours ahead of EST. During US EDT, AEST is 14 hours ahead.

When it is 9:00 AM in Sydney (AEST), what time is it in New York?

When it is 9:00 AM AEST in Sydney, it is 6:00 PM EST the previous day in New York. During EDT, 9:00 AM AEST = 7:00 PM EDT the prior evening.

What is the best time to call between Sydney and New York?

The most practical window is 7:00–9:00 AM EST (New York), which is 10:00 PM–midnight AEST in Sydney. Alternatively, 5:00–7:00 PM AEST = 2:00–4:00 AM EST — which almost never works for business.
