About Eastern Daylight Time (EDT)
Eastern Daylight Time (EDT, IANA: America/New_York during DST window) is the summer-time variant of EST, set at UTC-4:00 — observed from the second Sunday in March to the first Sunday in November per the US Energy Policy Act of 2005. EDT shares the same UTC offset as Atlantic Standard Time (AST — observed year-round in Canadian Maritimes Nova Scotia/New Brunswick/PEI and in Caribbean Puerto Rico/USVI/Bermuda) and as Bolivia/Chile/Paraguay Standard Time. The 'spring forward' transition at 02:00 EDT in March is the largest single coordinated time change in human history, affecting ~150 million US East Coast residents simultaneously per US Census. Florida passed the Sunshine Protection Act in 2018 attempting to stay on EDT year-round, but it required US Congressional approval (US Code 15 §260a) which has not been granted as of 2024. EDT affects: US Federal Government tax-filing deadlines (IRS Form 1040 due 23:59 EDT on April 15), NFL Sunday Night Football scheduling, and US Supreme Court oral-argument schedules in DC.
About Australian Western Standard Time (AWST)
Australian Western Standard Time (AWST, IANA: Australia/Perth) is the civil time of Western Australia (WA), set at UTC+8:00 year-round (no DST). Western Australia has rejected Daylight Saving Time in four separate referendums (1975, 1984, 1992, 2009 — each time defeated), so AWST is observed without seasonal change despite the rest of Australia (eastern states) observing AEDT in summer. The unusual situation creates a 3-hour offset between Perth (AWST = UTC+8) and Sydney (AEDT = UTC+11) in summer, vs. the standard 2-hour offset in winter (AWST UTC+8 vs AEST UTC+10). AWST is identical in offset to China Standard Time (CST), Singapore Time (SGT), Hong Kong Time (HKT), Philippine Time (PHT), Malaysia Time (MYT). AWST serves approximately 2.8 million Western Australian residents — the world's largest sub-national area on a single time zone (WA is 2.527 million km² = larger than Western Europe). Major AWST cities: Perth (2.1M metro — Australia's 4th-largest city), Mandurah (95K), Bunbury (75K), Geraldton (40K), Kalgoorlie-Boulder (30K — gold mining hub), Albany (35K — historic whaling port), Broome (15K — pearl industry + tourism), Karratha (15K — Pilbara iron-ore export hub). Affects: ASX (Australian Securities Exchange) operations from Perth offices, Rio Tinto / BHP Pilbara iron-ore shipping coordination.
