Translate to your time zone.
In the Northern Hemisphere, the sun is rising later now, and nightfall comes sooner. The time of the autumn equinox is here, when the days are getting shorter, and day and night are approximately equal in length.
For us in the Northern Hemisphere, people are enjoying the cooler days of autumn even as preparations for winter are underway. South of the equator, spring begins.
