About Newfoundland Standard Time (NST)
Newfoundland Standard Time (NST, IANA: America/St_Johns) is one of the world's few time zones with a 30-minute offset, set at UTC-3:30. NST is observed exclusively in the Canadian province of Newfoundland and Labrador (the island portion of the province and southeastern Labrador), serving approximately 500,000 residents. The 30-minute offset is preserved from the 1884 International Meridian Conference compromise that established time zones — Newfoundland Time was chosen because the island's longitudinal position (52.7°W central meridian for St. John's) falls between Atlantic and Eastern time zones, and the province's parliament voted to keep its own dedicated offset rather than align with neighboring provinces. NST observes Daylight Saving Time per the Canadian aligned schedule (switching to NDT = UTC-2:30 from March to November). Other 30/45-minute offset zones globally: India (IST UTC+5:30), Nepal (UTC+5:45), Myanmar (UTC+6:30), Iran (UTC+3:30), Afghanistan (UTC+4:30), Sri Lanka (UTC+5:30), Marquesas (UTC-9:30). NST affects: cod-fishing and offshore oil platform operations on the Grand Banks, ferry schedules to Cape Breton, and the historic Cabot Tower St. John's noon-gun.
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.
