About GMT (Greenwich Mean Time)
Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.
About EEST (Eastern European Summer Time)
Eastern European Summer Time (EEST) is the daylight saving period used across eastern Europe, when clocks move one hour forward from Eastern European Time (EET, UTC+02:00) to UTC+03:00. It runs from the last Sunday in March to the last Sunday in October, in step with the rest of the European Union. EEST covers Greece, Finland, Romania, Bulgaria, the Baltic states, Ukraine and Moldova, and matches the offset used year-round by Moscow, Istanbul and Riyadh during those months. Athens and Helsinki both sit near the western edge of the EEST band, so summer evenings stay light well past 21:00.
