About Australian Eastern Standard Time (AEST)
Australian Eastern Standard Time (AEST, IANA: Australia/Sydney) is the civil time of Australia's most populous eastern states — New South Wales (NSW), Victoria (VIC), Queensland (QLD), Tasmania (TAS), Australian Capital Territory (ACT) — set at UTC+10:00. AEST is observed in winter; NSW + VIC + TAS + ACT switch to Australian Eastern Daylight Time (AEDT = UTC+11) from the first Sunday of October to the first Sunday of April. Queensland does NOT observe DST (stays on AEST year-round) — a state-level decision affirmed by referendums in 1992. AEST serves approximately 21 million Australians — about 80% of the country's population. AEST is identical in offset to Vladivostok Time (Russia), Papua New Guinea Time (PGT), Guam-Chamorro Time (CHST), and the US-territory Northern Mariana Islands. Major AEST cities: Sydney NSW (5.4M metro — largest Australian city + ASX home), Melbourne VIC (5.1M metro — 2nd-largest), Brisbane QLD (2.6M metro — 3rd-largest, on AEST year-round), Gold Coast QLD (725K — tourist coastline), Newcastle NSW (475K), Canberra ACT (450K — federal capital), Hobart TAS (250K — Tasmanian capital). Affects: ASX trading hours 10:00-16:00 AEST, Australian Cricket / AFL game scheduling, Great Barrier Reef + Sydney Opera House tourism operating hours.
About Pacific Daylight Time (PDT)
Pacific Daylight Time (PDT, IANA: America/Los_Angeles during DST window) is the summer-time variant of PST, set at UTC-7:00 — observed from the second Sunday in March to the first Sunday in November per the Energy Policy Act of 2005, which extended the US DST window by ~4 weeks compared to the prior Uniform Time Act of 1966 schedule. PDT is the same offset as Mountain Standard Time (MST), creating a confusing situation where Arizona (which doesn't observe DST and stays on MST year-round) shares the same clock as California during summer months but is one hour behind during winter. PDT is used by ~50 million people in California, Oregon, Washington, Nevada, British Columbia, Yukon, and Baja California Norte. Affects: West-Coast NYSE/Nasdaq market open shifts to 06:30 PDT, professional sports West Coast game-time broadcasts to East Coast PDT prime time, and US Pacific Fleet operations from Naval Base San Diego.
