EST to AEST: 2026 Time Converter & Meeting Times
EST is Eastern Time (US) (UTC-5/-4) and AEST is Australian Eastern Time (UTC+10/+11). Below is a live conversion with real-time clocks using New York and Sydney as representative cities. DST rules are applied automatically using IANA time zone data.

Understanding EST and AEST in 2026
Time zone abbreviations like EST and AEST are handy shorthand, but they hide a trap: several regions reuse the same letters, and many switch their underlying offset twice a year for daylight saving. EST maps to Eastern Time (US) and AEST maps to Australian Eastern Time here. Rather than memorising raw offsets, check the live conversion above -- it uses today's date and the IANA time zone database, so you never get it wrong.
For meetings with three or more locations, drop the cities into the meeting planner, which computes the live overlap with daylight saving baked in for every city at once.
Frequently Asked Questions: EST to AEST
What is the time difference between EST and AEST in 2026?
AEST (Australian Eastern Time, UTC+10/+11) and EST (Eastern Time (US), UTC-5/-4) are in different time zones. The exact gap is shown live above using IANA time zone data. Where a time zone observes daylight saving, the gap shifts by 1 hour seasonally -- this tool always uses the current rule.
When it's 9:00 AM EST, what time is it in AEST?
Check the live hourly conversion table above. Because EST and AEST may each observe DST on different schedules, the conversion depends on the current date. The green rows show when AEST is in working hours.
What does EST stand for?
EST stands for Eastern Time (US), with a UTC offset of UTC-5/-4. AEST stands for Australian Eastern Time, with a UTC offset of UTC+10/+11. Note that some abbreviations like CST are reused across regions (China Standard Time vs Central Standard Time) -- always check the full time zone name to avoid confusion.
Is EST the same year-round?
No. EST (Eastern Time (US)) changes between standard and daylight time. The standard offset is UTC-5 and the daylight offset is -4.
Is AEST the same year-round?
No. AEST (Australian Eastern Time) changes between standard and daylight time. The standard offset is UTC+10 and the daylight offset is +11.
What cities use EST and AEST?
EST (Eastern Time (US)) includes New York, United States. AEST (Australian Eastern Time) includes Sydney, Australia. Use the interactive meeting planner to add specific cities.
How do I convert between EST and AEST for recurring meetings?
Bookmark this page and check it at the start of each season. Because at least one of these time zones observes DST, the conversion may shift by 1 hour during DST transitions. The live table above always uses the current date so you see the correct conversion.
