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!
