Probably the biggest highlight of September is that, on September 22nd, Fall officially begins in the Northern Hemisphere and Spring begins in the Southern Hemisphere. This is called the Autumnal Equinox, which is when the Sun's path crosses our Equator. Regardless of what you may have heard or will hear today, this has nothing to do with being able to balance an egg on end. You can balance an egg on its end any time as long as you have patience.
It does mean that the days will continue to grow shorter as the month goes on. If you check the calendar at the right of the page, you can see that the days at the end of September are nearly an hour shorter than they are at the beginning of the month.
