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.
About AST (Atlantic Standard Time)
Atlantic Standard Time (AST) covers Canada's Atlantic provinces (Nova Scotia, New Brunswick, Prince Edward Island, and most of Labrador), as well as several Caribbean nations. Puerto Rico and the US Virgin Islands use AST year-round without daylight saving time. The Canadian provinces switch to Atlantic Daylight Time (ADT) in summer.
