MUNDANE MYSTERIES: How many Friday the 13th’s do we get in a year?

If you haven’t heard yet today is Friday the 13th! Be careful out there… 

Today’s mystery… how many times does a Friday the 13th happen in one year?

Each calendar year has at least one Friday the 13th in it, and at the most three of them. You would get three Friday the 13th days in a calendar year if January 1st fell on a Sunday in a leap year (2012 was the last time that happened), or if January 1st fell on Thursday in a non-leap year (2015 was the last time.)

The last time we only had 1 was 2016. Exciting! Hopefully you’re not having any bad luck today.
