About Western European Time (WET)

Western European Time (WET, IANA: Europe/Lisbon, Atlantic/Faroe) is the civil time during winter for Portugal mainland (excluding the Azores), the Canary Islands (Spain), the Faroe Islands (Denmark), and Iceland uses WET-equivalent year-round (no DST in Iceland). WET is set at UTC+0 — the same offset as GMT — but the distinction is that GMT refers specifically to the time at the Greenwich Observatory while WET is the formal civil-time designation in continental Western European countries. WET observes Daylight Saving Time (switching to WEST — Western European Summer Time = UTC+1) from the last Sunday of March to the last Sunday of October per EU Directive 2000/84/EC. The Azores archipelago (Portuguese Atlantic territory) is one hour behind mainland Portugal at AZOT = UTC-1:00 (winter) / AZOST = UTC+0:00 (summer). WET serves approximately 17 million people. Major cities: Lisbon (550K city, 2.9M metro), Porto (240K), Las Palmas de Gran Canaria (380K), Santa Cruz de Tenerife (220K), Reykjavík (130K — Iceland on WET-equivalent), Tórshavn Faroe (13K).

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.
