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 Korea Standard Time (KST)
Korea Standard Time (KST, IANA: Asia/Seoul) is the civil time of both the Republic of Korea (South Korea) and the Democratic People's Republic of Korea (North Korea — since May 2018 when North Korea reverted to KST from its briefly used Pyongyang Time UTC+8:30 of 2015-2018), set at UTC+9:00 year-round (no DST). South Korea observed Daylight Saving Time briefly in 1948-1951 and again 1987-1988 during the Seoul Olympics (to facilitate evening TV broadcasts to North America), but discontinued it both times. KST is identical in offset to Japan Standard Time (JST), Yakutsk Time, Western Indonesian Time WIT (eastern Indonesia), and Palau Time (PWT) — creating a 'business-friendly' Northeast Asia zone of synchronized financial centers (Seoul-Tokyo). KST serves the Korean Peninsula's approximately 78 million residents (South Korea 52M + North Korea 26M). Major KST cities: Seoul (9.7M city, 25.7M metro — South Korean capital and the world's 5th-largest metro), Busan (3.3M — South Korea's 2nd-largest city + main port), Incheon (3M — Seoul Capital Area, location of Incheon International Airport ICN), Daegu (2.4M), Daejeon (1.5M), Pyongyang (3.2M — North Korean capital), Hamhung (770K — North Korea), Nampo (980K — North Korea). Affects: KRX (Korea Exchange) trading hours, K-pop industry music-release timing, Samsung + LG + Hyundai global headquarters operations.
