Every so often we get a back-to-back Friday the 13th, because February has 28 days 75.75% of the time. 2026 is one of those years. Exciting, no doubt!

March 13, be it a Friday or not, has an interesting history, and an occult position in the calendar year. In the USA, we write it as “3/13,” which alludes to the special prime number of “313,” though in Europe, the date is ordered as 13/3. The “313” in European date style happens on March 31 – 31/3.

313 is probably a number you haven’t thought much about, but the ancient world seemed to have a special place for it.

This brings us to the end of this blog piece, and given all that’s going on these days, I’m prepared for anything. I’m betting on an A.I. Jesus to show up in 2032. Seriously. They’re working on that event as we speak.
