About Greenwich Mean Time (GMT)
Greenwich Mean Time (GMT, IANA: Europe/London) is the historic and current civil time of the United Kingdom (during winter), Ireland (during winter), Portugal mainland (during winter), Iceland (year-round), and most West African countries. GMT is set at UTC+0 — the time on the Prime Meridian (0° longitude) running through the Royal Observatory in Greenwich, southeast London. Established as the global time reference by the 1884 International Meridian Conference in Washington DC, GMT served as the world's primary civil-time reference from 1884 until 1972 when UTC (Coordinated Universal Time) was adopted as the new precision standard. The UK switches from GMT to British Summer Time (BST = UTC+1) at 01:00 GMT on the last Sunday of March and back to GMT at 02:00 BST on the last Sunday of October per EU Directive 2000/84/EC (UK retained this schedule after Brexit). GMT affects: London Stock Exchange (LSE) trading hours, BBC World Service broadcast time-stamps, all aviation NOTAMs and weather METARs which use UTC = GMT, and ICAO + IMO worldwide maritime/aviation coordination.
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).
