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). Affects: TSE (Tokyo Stock Exchange) trading hours 09:00-15:00 JST, Tokyo Sumo Grand Tournaments, Shinkansen bullet-train scheduling, Tokyo Disney + USJ park operating hours.
About Central Daylight Time (CDT)
Central Daylight Time (CDT, IANA: America/Chicago during DST window) is the summer-time variant of CST, set at UTC-5:00 — observed from the second Sunday in March to the first Sunday in November per the US Energy Policy Act of 2005. CDT shares the same UTC offset as Eastern Standard Time (EST), so during winter months Chicago/Dallas are one hour behind New York/Atlanta, but during summer months Chicago/Dallas are still one hour behind because both regions advance equally for DST. The 'spring forward / fall back' transition affects an estimated 311 million US residents annually per Census data. CDT is used in 16 US states partially or fully (Illinois, Texas, Wisconsin, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Mississippi, Alabama, Tennessee, Kansas, Nebraska, Oklahoma, North Dakota, South Dakota) and parts of Canada (Manitoba, western Ontario, Saskatchewan partial — Saskatchewan stays on CST year-round, an exception). Affects MLB season game scheduling, CME / CBOT commodity trading hours, and US-Canada-Mexico USMCA cross-border supply-chain handoffs.
