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 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.
