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 EET (Eastern European Time)
Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya). During summer, most EET countries switch to Eastern European Summer Time (EEST, UTC+03:00). Turkey permanently moved to UTC+03:00 in 2016, effectively leaving EET.
