AST

Definition of AST

AST, or Atlantic Standard Time, refers to the time zone that is used in certain parts of North America, including Canada, Puerto Rico, and the US Virgin Islands. This time zone is four hours behind Coordinated Universal Time (UTC-4) during the winter months, and three hours behind (UTC-3) during the summer months when Daylight Saving Time is in effect.

In addition to being used in the Atlantic region, AST is also used in Alaska, which is located in the Alaskan Time Zone. This time zone is one hour behind Pacific Standard Time (UTC-9) during the winter months, and one hour behind Pacific Daylight Time (UTC-8) during the summer months.

Overall, AST is an essential time zone for those who reside or travel to regions that follow this method of timekeeping. Understanding the time differences and how they apply can help ensure that individuals arrive on time for appointments and other events, as well as helping to ensure efficient communication across regions.
