About Mountain Daylight Time (MDT)
Mountain Daylight Time (MDT, IANA: America/Denver during DST window) is the summer-time variant of MST, set at UTC-6:00 — observed from the second Sunday in March to the first Sunday in November per the Energy Policy Act of 2005. MDT shares the same UTC offset as Central Standard Time (CST), which can cause cross-time-zone scheduling confusion during the DST transition windows in March and November. The Navajo Nation in northeastern Arizona does observe MDT (unlike the rest of Arizona), creating one of the rare US sub-state time-zone exceptions per the Navajo Nation Council's 1968 resolution. MDT applies in Colorado, Utah, Wyoming, Montana, Idaho east, New Mexico, parts of Texas, and Canadian Rocky Mountain provinces (Alberta, eastern BC). Used in coordination of: Denver International Airport flight operations, ski-area lift hours during shoulder-season DST window, Yellowstone National Park ranger schedules, US National Renewable Energy Lab operations, and FAA Albuquerque ARTCC ATC operations.
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.
