October 13, 2017, is our second Friday the 13ths in 2017. Most calendar years have at least one Friday the 13th, but no more than three Friday the 13ths. The last time there was only one Friday the 13th in a calendar year was in May 2016 and the next time won’t be until August 2021. Did you know there were three Friday the 13ths in 2015 (February, March, November)? Yup, we survived! It will happen again in 2026. This year, in 2017, there are two Friday the 13ths (January and October). Today is it.

Now if you have friggatriskaidekaphobia – an irrational fear of Friday the 13th – Here’s something to consider this year’s second Friday the 13th on October 13, 2017, happens exactly 39 weeks (3 x 13 weeks) after the last Friday the 13th in January 2017. Just think 2018 is right around the corner and it has two Friday the 13ths. The first one comes on April 13, 2018, exactly 26 weeks (2 x 13 weeks) after the Friday the 13th in October 2017. Then the second Friday the 13th of 2018 falls on July 13, 2018, exactly 13 weeks after the first Friday the 13th in April 2018.

Just noting the coincidences involving the number 13.
