Local time in Buenos Aires (America/Argentina/Buenos Aires), daylight saving time included, rounded to the minute, for an open horizon at sea level.

Earliest sunset, latest sunrise

The shortest day in Buenos Aires is June 21, but the earliest sunset comes on June 11, at 5:49 PM, and the latest sunrise on June 29, at 8:01 AM. This shift comes from the equation of time: around the solstices, solar noon drifts by up to half a minute a day on the clock, so sunrise and sunset do not move symmetrically.

Solar noon and time zone

Buenos Aires lies at 34.60° south and 58.38° west. Its standard time, UTC−3, is set on the 45° west meridian, so the sun reaches its highest point in Buenos Aires about 54 minutes later than on that meridian. Over the year, solar noon falls between 12:37 PM (November 2) and 1:08 PM (February 11) on the clock.

Daylight saving time

Buenos Aires does not change its clocks (UTC−3 all year), so sunrise and sunset move only with the seasons: sunrise by 2 h 28 min and sunset by 2 h 21 min over the year.

Height of the sun and twilight

At solar noon the sun climbs to 78.8° above the horizon on December 21, and only 32.0° on June 21. Civil twilight, from first light to sunrise, lasts about 25 minutes at the March equinox and 28 minutes in late June. The day length changes fastest around March 14: 2 min 11 s less each day.

The sky gets fully dark every night of the year: even in midsummer, the sun sinks more than 18° below the horizon.
