About Atlantic Standard Time (AST)
Atlantic Standard Time (AST, IANA: America/Halifax, America/Puerto_Rico) is the time zone for the Canadian Maritime provinces and most of the Caribbean, set at UTC-4:00. AST is observed in: Nova Scotia, New Brunswick, Prince Edward Island, Labrador (partially), Newfoundland's Labrador portion, eastern Quebec, Puerto Rico, US Virgin Islands, Bermuda, Anguilla, Antigua, Aruba, Barbados, British Virgin Islands, Curaçao, Dominica, Grenada, Guadeloupe, Martinique, Saint Lucia, Saint Vincent, Trinidad and Tobago, and Venezuela (since 2007). Canadian Maritime provinces observe AST in winter and switch to ADT = UTC-3:00 in summer per the Energy Policy Act-aligned Canadian schedule. The Caribbean territories (Puerto Rico, USVI, Bermuda) and US territories observe AST year-round without DST per their territorial governments. AST is the same offset as EDT (Eastern Daylight Time) during US summer months, so Halifax and New York are on the same clock in summer but Halifax is one hour ahead in winter.
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.
