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 New Zealand Standard Time (NZST)

New Zealand Standard Time (NZST, IANA: Pacific/Auckland) is the civil time of New Zealand mainland (North Island + South Island), set at UTC+12:00. NZST is observed in winter; New Zealand switches to New Zealand Daylight Time (NZDT = UTC+13) from the last Sunday of September to the first Sunday of April per the Time Act of 1974 + Standard Time Act of 2007 (a slightly different DST schedule than Australia + most of the Northern Hemisphere). The Chatham Islands archipelago (Chatham, Pitt Islands — 800 km east of NZ mainland) uses Chatham Standard Time (CHAST = UTC+12:45) and Chatham Daylight Time (CHADT = UTC+13:45) — one of the world's only 45-minute-offset zones along with Nepal UTC+5:45 and Eucla WA UTC+8:45. NZST serves approximately 5.2 million New Zealanders. NZST is identical in offset to Fiji Time (FJT), Marshall Islands Time, Tuvalu Time, Wallis and Futuna Time. Major NZST cities: Auckland (1.7M metro — North Island), Wellington (210K city, 425K metro — capital), Christchurch (380K — South Island), Hamilton (180K), Tauranga (155K), Dunedin (135K), Queenstown (25K — tourist hub + Lord of the Rings filming locations). Affects: NZX (New Zealand Stock Exchange) trading hours, All Blacks rugby match scheduling, Hobbiton + Milford Sound tourism operating hours.
