The English phrase that treats Friday the 13th as unlucky is relatively modern. The often-cited Friday 13 October 1307 Templar arrests are a later bundling of date and weekday. Last Supper thirteen and Loki as a thirteenth guest are later popular cards. friday-the-13th lists dates; unlucky-number-13 is the numeral. This landing is a source sketch only. There is no agreed finding that crashes rise that day. Do not delay surgery for a calendar taboo.
The unlucky-Friday-the-13th sentence hardened in nineteenth- and twentieth-century Anglophone popular culture. It is not a single medieval European ban.
The arrests are an event. A straight line from that Friday to today’s horror films is overclaim.
