You may have used the expression “once in a blue moon” at some point or another, but do you actually know what it means? This phrase refers to something that is uncommon, or in some cases, rare. The term blue moon comes from the Farmers’ Almanac. The Farmers’ Almanac defined each season as having three full moons. If four moons occurred within one season, they referred to it as a blue moon.
Such is the case in August this year, when two full moons appear within the same calendar month. And don’t be fooled; the moon isn’t actually blue! On the first of the month, the initial full moon occurred. Friday marks the second and last chance to see a blue moon until 2015.
