Despite fall flavors taking over coffee shops and pumpkin decor popping up around town, Astronomical Fall does not officially begin this year until the Autumnal Equinox on September 22nd at 7:43 am. Equinox’s mark the two days a year when the sun is located directly above the equator and there are nearly equal amounts of daylight and nighttime. Beginning September 23rd, we will see daily daylight amounts continue to decline until it hitting a minimum at the Winter Solstice on December 21st.
