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

Boston gets 11h 44m of daylight today, from sunrise to sunset. Tomorrow will be 2 minutes 50 seconds shorter. Over the next seven days Boston loses 19 minutes 44 seconds of daylight.

That pace is not constant. In Boston the day length changes fastest around March, near the equinox, when it moves by about 2 minutes 53 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 Boston?

The earliest sunset of 2026 in Boston falls on 8 December at 16:11, 13 days before the December solstice, and the latest on 27 June at 20:25.

Sunrise runs on its own schedule: earliest on 14 June at 05:06, latest on 31 October at 07:16, the last morning before the clocks go back. One of these dates is pinned by the clocks rather than by the sky: a daylight saving change in Boston moves sunrise and sunset by a whole hour overnight, so the earliest and latest times on the clock land on either side of it. The rest is astronomy. 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.

These are wall-clock times, so Boston's daylight saving change is part of the picture: an hour moved by the clocks counts the same as an hour moved by the Earth.

The lower the angle at which the sun crosses the horizon, the longer twilight lasts, which is why dusk is a slow affair at high latitudes and abrupt near the equator.
