"When the Full Moon rises this Friday night, it will be the one of the rarest Harvest Moons ever!
The last time we saw a Friday the 13th Harvest Moon was in 1935 (technically), as the Full Moon rose on the night of Thursday, September 12 and set in the morning on Friday, September 13.
To have a Harvest Moon like we're seeing this Friday, however, with the Full Moon rising on September 13 and setting on September 14, you have to go back 152 years, to the year 1867!
The next time we'll see a Friday the 13th Full Moon will be in August of 2049, but for a Friday the 13th Harvest Moon, we'll have to wait much, much longer... until September of 2171!"
