"Blue moon, you saw me standing alone, without a dream in my heart, without a love of my own" a line from the song Blue Moon

Read on paper this morning: A blue moon will occur on August 30.

A blue moon is the extra full moon, or the 13th instead of only 12 full moons in a year. The blue moon is considered to be the second full moon in a calendar month.

Astronomers say that two full moons in one month may occur in any month except February, which is shorter than the lunar cycle.
