Is the day getting longer or shorter in Buenos Aires right now?
Buenos Aires gets 12h 27m of daylight today, from sunrise to sunset. Tomorrow will be 2 minutes 9 seconds longer. Over the next seven days Buenos Aires gains 15 minutes 3 seconds of daylight.
That pace is not constant. In Buenos Aires the day length changes fastest around March, near the equinox, when it moves by about 2 minutes 11 seconds per day, and it slows almost to a stop at the solstices in June and December. The word solstice means exactly that: the sun standing still.
When are the earliest and latest sunrise and sunset in Buenos Aires?
The earliest sunset of 2026 in Buenos Aires falls on 11 June at 17:49, 10 days before the June solstice, and the latest on 6 January at 20:10.
Sunrise runs on its own schedule: earliest on 5 December at 05:33, latest on 29 June at 08:01, 8 days after the June solstice. The four dates in the table below do not line up with the solstices, and they are not supposed to. Earth's orbit is slightly elliptical and its axis is tilted, so the sun runs a few minutes fast or slow against clock time through the year. That offset, the equation of time, is what pushes the earliest sunset ahead of the shortest day and the latest sunrise behind it.
| Extreme | Date | Local time | Why then |
|---|---|---|---|
| Earliest sunrise | 5 Dec 2026 | 05:33 | 16 days before the December solstice |
| Latest sunrise | 29 Jun 2026 | 08:01 | 8 days after the June solstice |
| Earliest sunset | 11 Jun 2026 | 17:49 | 10 days before the June solstice |
| Latest sunset | 6 Jan 2026 | 20:10 | 16 days after the December solstice |
