About Carolina Time Zone
Carolina, Puerto Rico uses the IANA time zone America/Puerto_Rico. Its standard offset is UTC-4, also commonly referred to as Atlantic Standard Time (AST). Puerto Rico stays on UTC-4 all year and does not observe daylight saving time, so the local time in Carolina remains stable across all seasons.
Carolina is part of the San Juan metropolitan area on the northeastern coast of Puerto Rico, and its time zone alignment is important for air travel, tourism, retail, and government services. Because Puerto Rico is a US territory, many people expect it to shift clocks like much of the mainland United States, but that does not happen here. This means the time relationship between Carolina and cities like New York or Chicago changes seasonally when those mainland locations enter or leave daylight saving time.
Relative to nearby regions, Carolina shares the same year-round UTC-4 offset as the US Virgin Islands and much of the eastern Caribbean that also stays on Atlantic Standard Time. During the Northern Hemisphere winter, Carolina is typically 1 hour ahead of New York when New York is on Eastern Standard Time (UTC-5). During the US daylight saving period, New York moves to UTC-4, so Carolina and New York match exactly for part of the year.

The country dialing codes used in Puerto Rico are +1-787 and +1-939; these are part of the North American Numbering Plan, so calling Carolina from the US or Canada works much like dialing another domestic North American number, depending on your carrier and plan.
