About Central European Summer Time (CEST)
Central European Summer Time (CEST, IANA: Europe/Berlin during DST window) is the summer-time variant of CET, set at UTC+2:00 — observed from the last Sunday of March to the last Sunday of October per EU Directive 2000/84/EC. CEST shares the same UTC offset as Eastern European Time (EET) (used by Greece, Romania, Finland, Estonia, Latvia, Lithuania, Bulgaria, Cyprus during winter), and is one hour ahead of Western European Summer Time (WEST). The 2018 European Commission proposal to abolish DST (with countries choosing to permanently stay on either standard time or summer time) has been delayed indefinitely as of 2024. CEST serves the same ~460 million population as CET across 27 European countries. The 'spring forward' transition at 02:00 CET on the last Sunday of March is one of the largest single coordinated time changes in human history. Affects: All European TV broadcast schedules (Eurovision Song Contest broadcast time), F1 European-round race start times, summer-music-festival schedules (Tomorrowland, Sziget, Glastonbury — UK on BST), and tourism arrival/check-in times in major European cities.
About Atlantic Standard Time (AST)
Atlantic Standard Time (AST, IANA: America/Halifax, America/Puerto_Rico) is the time zone for the Canadian Maritime provinces and most of the Caribbean, set at UTC-4:00. AST is observed in: Nova Scotia, New Brunswick, Prince Edward Island, Labrador (partially), Newfoundland's Labrador portion, eastern Quebec, Puerto Rico, US Virgin Islands, Bermuda, Anguilla, Antigua, Aruba, Barbados, British Virgin Islands, Curaçao, Dominica, Grenada, Guadeloupe, Martinique, Saint Lucia, Saint Vincent, Trinidad and Tobago, and Venezuela (since 2007). Canadian Maritime provinces observe AST in winter and switch to ADT = UTC-3:00 in summer per the Energy Policy Act-aligned Canadian schedule. The Caribbean territories (Puerto Rico, USVI, Bermuda) and US territories observe AST year-round without DST per their territorial governments. AST is the same offset as EDT (Eastern Daylight Time) during US summer months, so Halifax and New York are on the same clock in summer but Halifax is one hour ahead in winter.
