33 Days Left Till End of Summer, Autumn to Start on September 22's Noon

Only 33 days left until the end of the summer, as it will officially end on September 22. It lasted for 93 days, and 15 hours. 

According to astronomical studies, autumn will last for 89 days, and 20 hours which is the time of the autumn equinox. 

During an equinox, the Sun crosses the “celestial equator." The Sun’s center passes through the equator.

In the Northern Hemisphere, when the Sun crosses the equator from north to south, this is called the autumnal equinox, but for the Southern Hemisphere is the reverse.

After the autumnal equinox, days become shorter than nights as the Sun continues to rise later and night falls earlier, this slowly leads to the winter solstice.
