Rare full Harvest Moon will rise on Friday the 13th

The Friday the 13th won't be quite as rare in the Eastern time zone because the full moon technically happens just after midnight on the 14th.

So why is this timing so special?

According to the Farmer's Almanac, we haven't seen a combination like this since October 13th, 2000 and it won't happen again until August 13th, 2049.

Alena Kiel said: "Anyway so my birthday is on Friday the 13th and there's a Full Moon so I guess I'm gonna be extra powerful this year".

However, Americans in the Pacific, Central, Mountain and Alaskan time zones will witness the full moon on Friday 13-a day that is considered unlucky in Western superstition. While most moons rise approximately 50 minutes after sunset, the harvest moon can appear as soon as 10 minutes after the sun sets.

The Moon will appear full for about three days centered around this time, from Thursday night through Sunday morning, NASA reports.

However, this year's Harvest Moon is unlike most in that it will coincide with Friday the 13th.

"What sets this upcoming full moon apart from the others is that farmers, at the peak of the current harvest season, can work late into the night by this moon's light", explains the almanac.

According to the Farmers' Almanac, "It has been calculated that to have a full moon occur on the 13th day of a particular month, and for that day to be a Friday, it is (on average) a once in 20-year occurrence".

The opposite of a micromoon is a "supermoon" when the the moon is at perigee, or at the closest point to the Earth in its orbit.

Unless cloud cover blocks the view, the full moon is the easiest celestial event to observe.
