What is Atlantic Standard Time (AST)?
Atlantic Standard Time (AST) is a time zone that is 4 hours behind Coordinated Universal Time (UTC-4:00). It covers several regions in the Americas, including Puerto Rico, the U.S. Virgin Islands, Bermuda, and parts of Canada such as Nova Scotia, New Brunswick, and Prince Edward Island.
Because these regions generally do not observe daylight saving time (or remain on standard time year-round, depending on the specific location), the offset remains consistent for many users. Our live clock automatically tracks the current time, providing you with an accurate, hassle-free reading of the hour, minute, and second in the Atlantic time region.
