The days are short and the nights are long, usually in autumn. This is because the Earth's orbit is illuminated obliquely by the Sun, resulting in a difference in the length of time that the northern and southern hemispheres receive from the sun. At the autumnal equinox, the sun shines directly at the equator, and the hours of day and night are roughly equal, but as autumn progresses, the Northern Hemisphere receives less and less sunlight, resulting in short days and longer nights.
According to this phenomenon, it is common to refer to autumn as the season of "short days and long nights". During this season, people need to get used to the short days and long nights of 1110. For example, people need to wake up earlier to complete their tasks in a more limited amount of time.
