Every Full Moon on Halloween is always a Blue Moon

October is the Hunters moon. Second moon of any month is called a blue moon.

I always remember Rod Taylor singing it in “Fate is the Hunter.”

Every Full Moon on Halloween is always a Blue Moon

A full moon on Halloween occurs, on average about twice in 59 years. We happen to be in a period when the 19 year Metonic cycle lines up with the Gregorian Calendar. Full moons on Halloween occur every 19 years this century, 2001*, 2020, 2039, 2058, 2077, 2096. Also in 1925, 1944, 1955, and 1974, with near misses in 1963 and 1982. Any full moon on Halloween is a "blue moon" by the second full moon in calendar month definition.

*In 2001, the "full" moon was at 04:35 Nov 1 UT or 12:35 Nov 1, ET. It was still Halloween in the rest of the country, and the full moon was on the night of 31 Oct - 1 Nov, which I'm callin' "All Hallows E'en".

You are correct.

It was a bit on the chilly side here last night but when the bonfire burned down it sure was pretty hanging up there.
