UTC offset
UTC-04:00
Anguilla does not observe daylight saving time. Clocks stay on UTC-04:00 all year long.
Atlantic Standard Time (AST)
Atlantic Standard Time (AST, UTC−04:00) covers a broad swath of the Caribbean and parts of eastern Canada, where most islands stay on a steady year-round clock while a handful of Canadian zones shift forward in summer—making AST a mix of tropical consistency and northern-seasonal change.
Most Caribbean islands near the equator see very little variation in daylight throughout the year, so they keep a fixed offset (UTC−04:00) and skip daylight saving entirely.
A few Canadian zones—like parts of Nova Scotia and Quebec—follow Atlantic Daylight Time (ADT, UTC−03:00) in summer, shifting clocks forward by one hour.
There are 29 member zones under the AST umbrella, spanning independent nations, overseas territories, and Canadian provinces.
No. AST is one hour ahead of EST (UTC−05:00) and aligns with EDT (UTC−04:00) only when Eastern Time is observing daylight saving.
Anguilla’s location in the Caribbean means nearly equal day and night year-round, so there’s little benefit to shifting clocks.
AST was formalized in the early 20th century to standardize timekeeping across the Atlantic-facing Caribbean and parts of eastern Canada.
No. Only the Canadian zones that observe DST follow North American daylight saving schedules; the rest stay fixed.
Travel between most AST islands doesn’t require clock adjustments, but flying to or from Canadian AST zones in summer means a one-hour shift.
AST links Caribbean financial hubs and eastern Canadian markets, offering a stable time reference for cross-regional coordination.
