Get ready for the Harvest Moon. Depending on where you live on the planet, it’s either Wednesday or Thursday of this week.  

“In traditional skylore, the Harvest Moon is the full moon closest to the autumnal equinox,” EarthSky reports, “and depending on the year, [it] can come anywhere from two weeks before to two weeks after the autumnal equinox.” For 2013, that changing of the seasons happens on September 22 — just a few days from now.
