In the Northern Hemisphere, between September 23 and December 21, days become progressively shorter. This period marks the transition from the autumn equinox, when day and night are approximately equal, to the winter solstice, the shortest day of the year. As the sun's path in the sky lowers, daylight hours decrease, leading to longer nights. This change is a result of the tilt of the Earth's axis away from the sun during this time.
