About time in San Juan

San Juan keeps Atlantic Standard Time, UTC−4 from UTC all year. The offset never changes, so any difference between you and San Juan moves only when your own clocks do.

San Juan shares the zone America/Puerto_Rico with Bayamón, Carolina, Ponce, Punta Cana, so a time here is also the time there. One canonical page per zone keeps the difference honest: the settlement name changes, the clock does not.

Offsets and daylight saving rules come from the IANA time zone database — see IANA time zone notes for what that data does and does not promise about future dates.
