autumnal equinox

Today is the autumnal equinox (day and night are equal in length), which marks the beginning of fall in the northern hemisphere and spring in the south. Over the next three months, the Sun will move farther south in the sky so we will see less and less sunlight each day until after the winter solstice in December.
