How Rare is a Friday the 13th Full Moon?

Tomorrow morning, actually very early in the morning — 12:11 am to be exact, Eastern Time — the Moon will be Full and the date on the calendar is Friday the 13tth;  however, in many areas of the US and Canada, the Full Moon will take place on Thursday the 12th.! (Full Moon for the Central Mountain and Pacific time zones is on Thursday, the 12th)

A Friday the 13th full Moon happens on average once about every 14 years. Last time was October 2000 and the next time will be August 2049, so you could say it’s kind of rare.

Interestingly,  there was a Friday the 13th Moon in July 1984, and less than 3 years later there was another, in Feb. 1987.

And consider this for those places in the US that will not have Full Moon fall on the 13th this year, they haven’t had one since 2000 and must wait until 2049 for their next opportunity–almost half a century!

I was born on July Friday 13th full moon of 1984 so I find this article to be very interesting. I didn’t realize how rare the occurrence was. I feel kind of special ?. Also, apparently I’ve lived through 3 of them within a 32 year span whereas others will have to wait almost 50 years to see one so I feel a bit privileged as well. Neat article. Thanks

A full moon occurs every 29.5 days or so. A 13th of the month occurs every 28, 29, 30, or 31 days. A Friday the 13th occurs in one of seven months on an irregular schedule. So when one happens is very irregular, requires several irregular event to happen together.

My birthday is also tomorrow.

I was just wondering this actually, so thanks for the article. However, my birthday is also tomorrow. So, how rare is it to have a full moon on your Friday the 13th birthday? I’m thinking once in a lifetime!

On AVERAGE…. some are closer together, others are much further as part than the 14 year average.

@Doug – this is why it’s rare – it won’t happen in 2028. The key word is “average.”

9 Doug { 06.12.14 at 9:49 am }

if the average is about 14 years, shouldn’t the next Friday 13th with a full moon be in 2028 not August of 2049. Proof read before typing.

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
