It's Friday the 13th, again

Rico says we survive it every year or so, but there's still a lot of superstition about it:
The fear of Friday the 13th has been called triskaidekaphobia, meaning fear of the number thirteen.

Records of the superstition are rarely found before the twentieth century, when it became extremely common. The connection between the Friday the 13th superstition and the Knights Templar was popularized in Dan Brown's 2003 novel The Da Vinci Code, and in John J. Robinson's 1989 work Born in Blood: The Lost Secrets of Freemasonry. On Friday, 13 October 1307, hundreds of the Knights Templar were arrested in France, an action apparently motivated financially and undertaken by the efficient royal bureaucracy to increase the prestige of the crown. Philip IV was the force behind this ruthless move, but it has also tarnished the historical reputation of Pope Clement V. From the very day of Clement V's coronation, the King falsely charged the Templars with heresy, immorality, and abuses, and the scruples of the Pope were compromised by a growing sense that the burgeoning French State might not wait for the Church, but would proceed independently. However, experts agree that this is a relatively recent correlation, and most likely a modern-day invention.
