Atlantic Standard Time (AST)

Introduction

Atlantic Standard Time (AST) is a time zone used in parts of North America and the Caribbean. It is 4 hours behind Coordinated Universal Time (UTC-4). This time zone is observed in several regions, including parts of Canada, the Caribbean, and some U.S. territories. AST is known for its consistent timekeeping, as it does not observe daylight saving time in most areas.

Time Zone History

Atlantic Standard Time was established to standardize timekeeping across the Atlantic region. Historically, the region has undergone several changes in timekeeping practices, including shifts in time zone boundaries and adjustments for daylight saving time. The establishment of AST helped streamline these practices and provide consistency for residents and businesses.

Geographical Coverage

Atlantic Standard Time is observed in several regions, including parts of Canada (New Brunswick, Nova Scotia, Prince Edward Island, and parts of Quebec), the Caribbean (such as Puerto Rico, the U.S. Virgin Islands, and several other islands), and some U.S. territories. The time zone helps synchronize activities across these diverse areas, ensuring a unified schedule for economic and social activities.

Daylight Saving Time (DST)

Atlantic Standard Time does not observe daylight saving time in most regions. However, some areas, such as parts of Canada, switch to Atlantic Daylight Time (ADT) during the summer months, moving the clocks forward one hour to UTC-3. This practice helps make better use of daylight during the longer summer days.
