Time Zone & Daylight Saving Guide for Dominican Republic
Official Regional Time Standard: The official time zone for Dominican Republic is Atlantic Standard Time (AST). Its legally designated baseline offset from the Prime Meridian is UTC-4 (Year-Round) under the international IANA coordinate identifier America/Santo_Domingo.
Daylight Saving Exemption: Unlike the majority of North American jurisdictions, Dominican Republic operates under a permanent standard time policy (No DST). It does not adjust its clocks forward in spring or backward in autumn. As a result, its relative time difference with neighboring states shifts by one hour twice each year when other jurisdictions transition into or out of Daylight Saving Time.
