Central European Time (CET/CEST). Paris, Berlin, Madrid, Rome, Amsterdam, Brussels, Vienna, Warsaw and most of the European Union. CET is UTC+1; in summer it is CEST, UTC+2.
Sunday, March 28, 2027: clocks go forward 1 hour at 2:00 AM local time (UTC+1 → UTC+2).
Atlantic Time (AST/ADT). Nova Scotia, New Brunswick and Prince Edward Island (with daylight saving), plus Puerto Rico and much of the Caribbean, which stay on AST (UTC−4) all year.
Sunday, March 14, 2027: clocks go forward 1 hour at 2:00 AM local time (UTC−4 → UTC−3).
The current difference is shown at the top of this page. CET uses Central European Standard Time (CET, UTC+1) as standard time and Central European Summer Time (CEST, UTC+2) during daylight saving time; AST uses Atlantic Standard Time (AST, UTC−4) as standard time and Atlantic Daylight Time (ADT, UTC−3) during daylight saving time. The difference can change if only one side observes daylight saving time or if their clocks change on different dates. Choose your meeting date in the converter to check the applicable offset.
