Convert ET to AEST
Eastern Time (ET) to Australian Eastern Time (AEST)
US-Australia teams deal with one of the trickiest timezone gaps in global business. The 14-16 hour difference means today in New York is already tomorrow in Sydney. Adding complexity, both countries observe DST but in opposite seasons, so the offset swings between 14 and 16 hours throughout the year.
When it's 12:00 PM in New York, it's 2:00 AM in Sydney (next day)
On Jan 1 – Mar 7, 2026; Nov 1, 2026 – Mar 13, 2027; Nov 7 – Dec 31, 2027: 4:00 AM in Sydney (next day).
On Mar 8 – Apr 4, 2026; Oct 4 – Oct 31, 2026; Mar 14 – Apr 3, 2027; Oct 3 – Nov 6, 2027: 3:00 AM in Sydney (next day).

Scheduling Tips
- The only reliable overlap is early morning US / late evening Australia. Try 7:00-8:00 AM EST / 11:00 PM-12:00 AM AEDT (Nov-Mar) or 7:00-8:00 AM EDT / 9:00-10:00 PM AEST (Apr-Oct) for brief syncs.
- Alternatively, schedule at 5:00-6:00 PM EST / 9:00-10:00 AM AEDT (next day, Nov-Mar) or 5:00-6:00 PM EDT / 7:00-8:00 AM AEST (next day, Apr-Oct) to catch the Australian morning.
- Rotate meeting times quarterly to share the inconvenience fairly between teams.
- Mark DST transition weeks on your calendar -- the offset can shift by a full hour, which matters when your overlap window is already narrow.
