Tridecalatry

Tridecalatry is the worship of number 13. Thirteen is globally the unlucky number. The unluckiness of the number came when Judas was the 13th person to sit at the Last Supper with Jesus Christ and 11 other people, and then ultimately hung himself in frustration. The root of the frustration was believed when God was mad at them. To soothe the eternal madness on Judas, God would bring bad luck to some people surrounding the number 13, such as a person having a bad day on the 13th or those wearing uniform #13 would have bad performances. The bad luck surrounding the number 13 can be reduced by worshipping that number that would make God proud.
