Frequently Asked Questions
What is the time difference between AWST and EDT?
During standard time, Eastern Daylight Time is 12 hours behind Australian Western Standard Time.
Does Perth observe Daylight Saving Time?
Perth and the rest of Western Australia do not observe Daylight Saving Time. Western Australians have voted against DST in multiple state referendums — most recently in 2009 — and AWST remains permanently fixed at UTC+08:00 throughout the year.
Are AWST and China Standard Time the same?
AWST and China Standard Time (CST) share the exact same UTC+08:00 offset, meaning Perth and Beijing operate on an identical clock. The same applies to Singapore Time (SGT) and Malaysia Time (MYT) — all three are perfectly synchronized with AWST, eliminating offset calculations entirely for the resource and commodity trade flows that connect Perth to these major Asian markets.
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.
