(CNN) — Yet another Friday the 13th has arrived, bringing the usual superstitious chatter along with vows to avoid flying and other fear-inducing activities. Why are we so weird about the 13th?
The answer is unclear but our aversion may have religious origins. Some Christians believe Friday is unlucky because it’s the day Jesus was crucified, and 13 signifies the number of guests at the Last Supper, with the infamous Judas being the 13th person seated at the table. Followers of numerology have long testified to the unsettling power of the numeral.
Whether you think it’s unlucky or not, cross your fingers and check out these 13 fun facts about Friday the 13th and our collective aversion to the number 13.

12. Tuesday is also terrifying
In some Spanish-speaking countries, Tuesday (Martes) the 13th is considered bad luck. Tuesday is feared because it is the day of the week associated with the Roman god of war, Mars. There is a cautionary saying: “On Tuesdays, don’t get married, don’t take a trip and don’t leave your home.”
13. Throwing caution to the wind
Founded in 1882 by Capt. William Fowler, The Thirteen Club of New York was a group of skeptics who defied superstitions by hosting dinner parties on Friday the 13th. At the first dinner, the 13 members performed such unlucky feats as passing under a ladder. They dined on 13 courses, the first by the light of 13 candles. The devil-may-care group tipped over salt containers on the table but were forbidden from tossing any of the spilled granules over their shoulders. The small club evolved into a national organization that boasted such members Grover Cleveland and Theodore Roosevelt, according to the New York Historical Society.
