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 Eastern Standard Time (EST)
Eastern Standard Time (EST, IANA: America/New_York, America/Toronto) is the time zone for the US Eastern Seaboard and Canadian eastern provinces, set at UTC-5:00. EST is the most economically and politically significant US time zone, serving the NYC-Washington DC-Boston-Atlanta-Miami corridor of ~150 million people across the entire US Eastern region (New York, Pennsylvania, Massachusetts, Connecticut, Rhode Island, Vermont, New Hampshire, Maine, New Jersey, Delaware, Maryland, Virginia, West Virginia, North Carolina, South Carolina, Georgia, Florida except panhandle, Ohio, Kentucky eastern, Tennessee eastern, Indiana most, Michigan most), eastern Canada (Quebec, Ontario), and the Caribbean (Bahamas, Cuba, Jamaica, Haiti, Panama since 1908). EST observes DST per Energy Policy Act 2005 (switching to EDT = UTC-4:00 from March to November). NYSE official market hours 09:30-16:00 EST/EDT, Wall Street financial reporting, US Federal Government Washington DC working hours, and US Capitol legislative sessions all reference EST/EDT. The historical 'Big Three' US TV-network prime-time was 8-11 PM EST.
