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 Western Indonesian Time (WIB)

Western Indonesian Time (WIB — Waktu Indonesia Barat, IANA: Asia/Jakarta) is the civil time of western Indonesia, set at UTC+7:00 year-round (no DST). Indonesia spans 3 time zones (WIB UTC+7, WITA UTC+8, WIT UTC+9) covering its 17,508+ island archipelago across ~5,000 km of longitude — the world's largest archipelagic country by area. WIB serves approximately 200 million Indonesian people on Java, Sumatra, West Kalimantan, and Central Kalimantan — including the major population centers. WIB is identical in offset to Indochina Time (ICT) used by mainland Thailand/Vietnam/Cambodia/Laos. Major WIB cities: Jakarta (10.5M city, 35M metro — Indonesia's capital and Southeast Asia's largest metro after Tokyo/Delhi/Shanghai/Manila), Surabaya (2.9M city, 9.3M metro — East Java capital), Medan (2.4M — Sumatra), Bandung (2.5M — West Java), Bekasi (3M — Jakarta satellite city), Tangerang (2.4M — Jakarta satellite), Depok (2.4M — Jakarta satellite), Semarang (1.7M — Central Java), Palembang (1.7M — Sumatra). Affects: IDX (Indonesia Stock Exchange) trading hours, Jakarta KRL commuter-rail schedules, Borobudur Buddhist temple + Prambanan Hindu temple tourism schedules.
