About the time in San Juan
The zone identifier America/Puerto_Rico is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Puerto_Rico keeps pointing at Puerto Rico time whatever the date, which is why every timestamp on this page is built from it.
San Juan runs on America/Puerto_Rico, which puts the city UTC −4 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
San Juan sits at latitude 18.45, in the tropical band, so day length here swings only a little between midwinter and midsummer — today's 12h 40m is one point on that curve, not a fixed value.
