About Alaska Standard Time (AKST)
Alaska Standard Time (AKST, IANA: America/Anchorage and America/Juneau) is the time zone for most of the State of Alaska, set at UTC-9:00. AKST is observed from the first Sunday in November to the second Sunday in March per the Uniform Time Act of 1966 + Energy Policy Act of 2005; Alaska switches to Alaska Daylight Time (AKDT = UTC-8:00) for the remainder of the year. The vast Alaska time zone covers ~3,200 km east-to-west — from Ketchikan to Atka in the Aleutians — and is the only US time zone that spans more than 1,000 miles longitudinally, meaning solar-noon in different Alaska cities varies by over an hour from local clock time. Major population centers: Anchorage (~290,000), Fairbanks (~95,000), Juneau state capital (~32,000). Used in coordination of cruise-ship schedules through the Inside Passage, North Slope oil-pipeline operations, US Air Force JBER and Eielson AFB activities, and Alaska commercial fishing season openings managed by ADF&G.
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.
