Is the day getting longer or shorter in Surabaya right now?

Surabaya gets 12h 10m of daylight today, from sunrise to sunset. Tomorrow will be 24 seconds longer. Over the next seven days Surabaya gains 2 minutes 49 seconds of daylight.

That pace is not constant. In Surabaya the day length changes fastest around March, near the equinox, when it moves by about 24 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 Surabaya?

The earliest sunset of 2026 in Surabaya falls on 24 May at 17:18, 28 days before the June solstice, and the latest on 29 January at 17:55.

Sunrise runs on its own schedule: earliest on 14 November at 05:00, latest on 16 July at 05:42, 25 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.
