About the time in Buenos Aires
The zone identifier America/Santo_Domingo is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Santo_Domingo keeps pointing at Santo Domingo time whatever the date, which is why every timestamp on this page is built from it.
Buenos Aires runs on America/Santo_Domingo, 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.
Sunrise today lands at 06:18 and sunset at 06:56 local time, giving 12h 38m of daylight. Those figures come from the city's own coordinates (18.84, -68.67) rather than a country-wide average, so they match what you would actually see from a window in Buenos Aires.
