September 23 is the 267th day of the year 2012. There are 99 days remaining until the end of the year, 44 days until the presidential election and is frequently the convergence of two stellar events: the birth of Saint John Coltrane and the autumnal equinox (Sept 22nd in 2012) the "equinox" spans several days before AND after that date.
The Fall Equinox is also known as: Alban Elfed, Autumn Equinox, Autumnal Equinox, Cornucopia, Feast of Avilon, Festival of Dionysus, Harvest Home, Harvest Tide, Mabon, Night of the Hunter, Second Harvest Festival, Wine Harvest, Witch's Thanksgiving, and the first day of autumn. Many religious festivals occur on or near the equinox for example, Rosh Hashanah began in the evening of Sunday, September, 2012, and ended in the evening of Tuesday, September, 2012. Michaelmas (also known as the Feast of Michael and All Angels), on September 29, falls near the September equinox.
