Frequently Asked Questions
What is the time difference between EDT and AEDT?
During standard time, Australian Eastern Daylight Time is 15 hours ahead of Eastern Daylight Time.
When does EDT start and end?
EDT begins on the second Sunday in March at 02:00 local time, when clocks spring forward one hour from EST (UTC-5) to EDT (UTC-4). It ends on the first Sunday in November at 02:00 local time, when clocks fall back to EST. In 2026, EDT runs from March 8 through November 1.
Is EDT the same as EST?
EDT and EST are two phases of the same Eastern Time zone, not two separate zones. EST (Eastern Standard Time) is the winter offset at UTC-5, observed from early November through mid-March. EDT (Eastern Daylight Time) is the summer offset at UTC-4, active during Daylight Saving Time — meaning New York and Toronto run one hour ahead of their winter clock for roughly eight months of every year.
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.
