About Eastern Daylight Time (EDT)
Eastern Daylight Time (EDT, IANA: America/New_York during DST window) is the summer-time variant of EST, set at UTC-4:00 — observed from the second Sunday in March to the first Sunday in November per the US Energy Policy Act of 2005. EDT shares the same UTC offset as Atlantic Standard Time (AST — observed year-round in Canadian Maritimes Nova Scotia/New Brunswick/PEI and in Caribbean Puerto Rico/USVI/Bermuda) and as Bolivia/Chile/Paraguay Standard Time. The 'spring forward' transition at 02:00 EDT in March is the largest single coordinated time change in human history, affecting ~150 million US East Coast residents simultaneously per US Census. Florida passed the Sunshine Protection Act in 2018 attempting to stay on EDT year-round, but it required US Congressional approval (US Code 15 §260a) which has not been granted as of 2024. EDT affects: US Federal Government tax-filing deadlines (IRS Form 1040 due 23:59 EDT on April 15), NFL Sunday Night Football scheduling, and US Supreme Court oral-argument schedules in DC.
About China Standard Time (CST)
China Standard Time (CST, IANA: Asia/Shanghai) is the unified civil time of the People's Republic of China, set at UTC+8:00 year-round (no DST). Despite China's vast east-west extent (~5,200 km from Xinjiang's western border at 73°E to Heilongjiang's eastern border at 135°E — 62° of longitude or ~4 hours of solar time), the entire country uses a single time zone since 1949 (consolidated from 5 separate zones used during the Republic of China era). This means Kashgar Xinjiang sees solar noon at approximately 14:00 CST in summer, while Shanghai sees solar noon at approximately 11:50 CST — a stark practical discrepancy. Hong Kong Time (HKT) and Macau Time (MOT) are identical at UTC+8 but use different IANA identifiers for historical reasons. CST serves approximately 1.42 billion people. CST is identical in offset to Singapore Time (SGT), Malaysia Time (MYT), Philippine Time (PHT), Australian Western Standard Time (AWST), Hong Kong Time (HKT). Major CST cities: Shanghai (24M), Beijing (21.5M), Chongqing (32M), Guangzhou (15M), Shenzhen (12.5M), Chengdu (16.3M), Tianjin (13.7M), Wuhan (11M), Xi'an (13M), Hangzhou (11.9M). Affects: SSE + SZSE stock exchanges, Beijing Central Government working hours.
