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 Central Standard Time (CST)
Central Standard Time (CST, IANA: America/Chicago, America/Mexico_City) is the time zone for the US Central region, central Mexico, and most of Central America, set at UTC-6:00. CST is the most populous US time zone by area covered and serves the Chicago-Dallas-Houston-Minneapolis corridor of ~80 million people across CST states (Texas, Illinois, Wisconsin, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Mississippi, Alabama, Tennessee western, Kansas eastern, Nebraska eastern, Oklahoma, North Dakota, South Dakota, Kentucky western, Indiana western, Michigan UP, Florida panhandle) plus Mexico (Mexico City, Guadalajara, Monterrey since 2022 DST abolition), Honduras, Nicaragua, El Salvador, Costa Rica, Guatemala, Belize. CST observes DST (switching to CDT = UTC-5:00) per Energy Policy Act 2005 — except for Mexico nationally, which abolished DST in 2022 except for border zones aligning with US DST. CST affects: NYSE close at 15:00 CST, CME (Chicago Mercantile Exchange) commodity futures pit/electronic hours, Texas Medical Center coordinated patient handoffs.
