Frequently Asked Questions
What is the time difference between AEST and PDT?
During standard time, Pacific Daylight Time is 17 hours behind Australian Eastern Standard Time.
Does all of eastern Australia observe Daylight Saving Time?
No — eastern Australia is split on DST. New South Wales (Sydney), Victoria (Melbourne), Tasmania (Hobart), and the ACT (Canberra) advance their clocks to AEDT (UTC+11) each October, while Queensland (Brisbane) opts out entirely and remains on AEST (UTC+10) year-round. This means Sydney and Brisbane run on the same clock for only part of the year.
What is the difference between AEST and AEDT?
AEST (Australian Eastern Standard Time) is the UTC+10:00 offset observed during the Southern Hemisphere winter months, roughly April through October. AEDT (Australian Eastern Daylight Time) is the UTC+11:00 offset applied during the Southern Hemisphere summer when clocks spring forward in October, observed by New South Wales, Victoria, Tasmania, and the ACT.
When does PDT start and end?
PDT begins on the second Sunday in March at 02:00 local time, when clocks spring forward one hour from PST (UTC-8) to PDT (UTC-7). It ends on the first Sunday in November at 02:00 local time, when clocks fall back to PST. In 2026, PDT runs from March 8 through November 1 — covering the majority of the calendar year.
Is PDT the same as PST?
PDT and PST are two phases of the same Pacific Time zone, not two separate zones. PST (Pacific Standard Time) is the winter offset at UTC-8, observed from early November through mid-March. PDT (Pacific Daylight Time) is the summer offset at UTC-7, active during Daylight Saving Time — meaning Los Angeles, Seattle, and Vancouver run one hour ahead of their winter clock for approximately eight months of every year.
