Frequently Asked Questions
What is the time difference between NZST and AEDT?
During standard time, Australian Eastern Daylight Time is 1 hours behind New Zealand Standard Time.
Does New Zealand observe Daylight Saving Time?
New Zealand observes Daylight Saving Time annually, advancing clocks to New Zealand Daylight Time (NZDT) at UTC+13:00 on the last Sunday of September and returning to NZST (UTC+12:00) on the first Sunday of April. In 2026, clocks spring forward on September 27 and fall back on April 5 — following the Southern Hemisphere calendar, which runs opposite to DST schedules in Europe and North America.
Why does Antarctica use New Zealand Time?
McMurdo Station and Amundsen-Scott South Pole Station — the two largest US Antarctic research bases — operate on NZST and NZDT because their primary supply and personnel flights operate out of Christchurch International Airport in New Zealand. Aligning base operations with New Zealand time eliminates scheduling complexity across the Christchurch–McMurdo logistics chain, which handles all cargo, fuel, and personnel rotations for the US Antarctic Program.
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.
