What happens during autumn?
The sun passes directly over the equator two times during the year. Each time this happens it is called the Equinox. This is the time when the daylight period and the night time are as equal in length as they can get. One is called the Vernal Equinox (indicating that spring is on the way) and the other is called the Autumnal Equinox (indicating that autumn is coming). These events happen in March and in September. Whether you are heading for spring or autumn depends on where you live on earth. In the north, autumn begins with the equinox in September. If you live in the southern hemisphere, spring begins in September! For people in the north, the sun is moving downward toward the equator and stays below the equator during the autumn and winter seasons. As the sun moves higher for people in the north, it is moving downward for people in the south. At the equinox in March, spring begins in the north and autumn begins for the south!
