New York City operates on Eastern Time — Eastern Standard Time (EST, UTC−5) in winter and Eastern Daylight Time (EDT, UTC−4) in summer. US clocks spring forward on the second Sunday of March and fall back on the first Sunday of November. NYSE and NASDAQ market hours (9:30 AM–4:00 PM ET) make Eastern Time one of the most referenced zones in global finance.
Sydney uses Australian Eastern Standard Time (AEST, UTC+10) in winter and Australian Eastern Daylight Time (AEDT, UTC+11) in summer. Because Australia is in the Southern Hemisphere, its summer runs October–April — the opposite of the Northern Hemisphere. Clocks go forward on the first Sunday of October and back on the first Sunday of April.
Both EST and AEST may observe Daylight Saving Time, which means the offset between them can change twice a year. Here is what to expect each season.
| Period | Note | EST | AEST | Offset |
|---|---|---|---|---|
| Nov – Mar | Both on standard time | EST (UTC−5) | GMT+11 (UTC+11) | 16 hours |
| Mar – late Mar | US clocks forward, some zones still on standard | EDT (UTC−4) | GMT+11 (UTC+11) | 15 hours |
| Late Mar – Oct current | Both on summer / daylight time | EDT (UTC−4) | GMT+10 (UTC+10) | 14 hours |
| Late Oct – early Nov | Clocks transitioning — check exact date | EST (UTC−5) | GMT+11 (UTC+11) | 16 hours |
The transition window typically lasts 1–2 weeks in spring and autumn. If you have a recurring weekly meeting near a clock change, verify the exact date to avoid a missed call.
EST is currently 14 hours behind AEST. EST uses Eastern Daylight Time (UTC−4) and AEST uses Australian Eastern Standard Time (UTC+10).
EST and AEST have no standard 9 am–6 pm business-hour overlap. Consider scheduling during early morning or late evening, or use a rotating schedule to share the inconvenience.
When it is 9:00 AM in EST, it is 11:00 pm in AEST. EST is 14 hours behind AEST.
When it is 5:00 PM in AEST, it is 3:00 am in EST.
Both EST and AEST observe Daylight Saving Time, but their transitions may not happen on the same date. During the brief 1–2 week windows in spring and autumn when only one zone has changed clocks, the offset between the two cities shifts by one hour. For most of the year the difference is 14 hours, but double-check the transition dates if you have a recurring meeting scheduled near those windows.
