About Atlantic Daylight Time (ADT)

Atlantic Daylight Time (ADT) is the daylight saving time observed in parts of the Atlantic region during the warmer months of the year. The time zone offset of ADT is UTC-03:00, which means it is 3 hours behind Coordinated Universal Time (UTC).

Atlantic Daylight Time is used in parts of eastern Canada, including Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador during the daylight saving period.

During the winter months, the region switches to Atlantic Standard Time (AST), which has a UTC offset of UTC-04:00.
