Frequently Asked Questions
What is the time difference between EST and AEDT?
During standard time, Australian Eastern Daylight Time is 16 hours ahead of Eastern Standard Time.
Is EST the same as Eastern Time (ET)?
Not exactly. 'Eastern Time' (ET) is a broad geographical term. EST is the specific UTC-05:00 offset used in winter, while EDT (Eastern Daylight Time) is the UTC-04:00 offset used during summer.
Does Florida use EST?
Most of Florida is in the Eastern Time Zone. However, the western part of the Florida Panhandle operates on Central Time (CST/CDT).
When does AEDT start and end?
AEDT begins on the first Sunday in October at 02:00 local time, when clocks spring forward one hour from AEST (UTC+10) to AEDT (UTC+11). It ends on the first Sunday in April at 03:00 local time, when clocks fall back to AEST. In 2026, AEDT starts on October 4 and ends on April 5 — following the Southern Hemisphere summer calendar, which runs opposite to DST schedules in Europe and North America.
Is Brisbane on AEDT?
No — Queensland, including Brisbane, does not observe Daylight Saving Time and remains on AEST (UTC+10) year-round. During the AEDT period from October through April, Sydney and Melbourne advance to UTC+11 while Brisbane stays at UTC+10, creating a one-hour gap between cities that share nearly the same longitude and are otherwise in the same time zone for the other six months of the year.
