About Mountain Standard Time (MST)
Mountain Standard Time (MST, IANA: America/Denver and America/Phoenix) is the time zone for the US Mountain region and most of Canada's Rocky Mountain provinces, set at UTC-7:00. MST is observed from the first Sunday in November to the second Sunday in March; the region switches to Mountain Daylight Time (MDT = UTC-6:00) for the remainder of the year — EXCEPT for the State of Arizona (excluding Navajo Nation), which stays on MST year-round per Arizona Revised Statutes §1-242. Major MST cities: Denver, Phoenix, Salt Lake City, Albuquerque, El Paso, Tucson, Calgary, Edmonton. MST covers Colorado, Utah, Wyoming, Montana, Idaho (most), New Mexico, Arizona, parts of Texas + Mexico (Sonora). Population ~17 million in the time zone. Affects: NORAD Cheyenne Mountain operations, Denver Mile-High Stadium NFL game scheduling, Colorado ski-resort lift-operating hours, US Bureau of Land Management permit operations, and the Mormon Tabernacle Choir broadcast schedule from Salt Lake City.
About Japan Standard Time (JST)
Japan Standard Time (JST, IANA: Asia/Tokyo) is the civil time of Japan, set at UTC+9:00 year-round (no DST). Japan observed Daylight Saving Time only briefly during American Occupation (1948-1951) and discontinued it after the Treaty of San Francisco. JST is also called Nippon Hyōjunji (日本標準時) and is officially maintained by the National Institute of Information and Communications Technology (NICT) — Japan operates a sophisticated atomic-clock-based timekeeping system at NICT Koganei facility with caesium beam frequency standards CSF-2 + Sr-87 optical lattice clock. JST is identical in offset to Korea Standard Time (KST), Yakutsk Time (Russian Far East), Western Indonesian Time WIT (eastern Indonesia), and Palau Time (PWT). JST serves Japan's approximately 125 million residents across 47 prefectures. Major JST cities: Tokyo (14M city, 37M metro — the world's largest metropolitan area by population), Yokohama (3.8M — Tokyo bay metro), Osaka (2.7M, Kansai region 19M metro), Nagoya (2.3M, Chukyo region 9.5M metro), Sapporo (1.9M — Hokkaido capital), Fukuoka (1.6M — Kyushu hub), Kobe (1.5M), Kawasaki (1.5M), Saitama (1.3M).
