There is no time difference between Santo Domingo and San Juan. Both cities use Atlantic Standard Time (AST, UTC-4). When it's 12:00 PM in Santo Domingo, it's also 12:00 PM in San Juan.
Neither the Dominican Republic nor Puerto Rico observes daylight saving time, so they remain synchronized year-round.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 5:00 PM) without any time conversion needed.
Santo Domingo and San Juan are neighboring Caribbean capitals on the island of Hispaniola and Puerto Rico respectively. They share cultural ties and have significant inter-island trade. Short flights connect them in about 45 minutes.
