Yes, it's Friday the 13th, folks, and there is actually a traditional word for it. Paraskevidekatria comes from the Greek language, where 'paraskevi' means Friday and 'dekatria' means the number 13.

The superstitions connected with this day are largely associated with Western culture, but thanks to the popular culture surrounding the number 13 itself, as well as Friday the 13th, it's seemingly almost a globally acknowledged tradition of sorts. In fact, the fear of the number 13 has its own medical name: paraskevidekatriaphobia; similarly, the intense and irrational fear of the number 13 is known as triskaidekaphobia.

It's believed that the word "paraskevidekatriaphobia" was devised by Dr Donald Dossey, who told his patients that "when you learn to pronounce it, you're cured!"

An observation made by CHL academic Dr Jane Ferguson in her paper titled, Terminally haunted: Aviation ghosts, hybrid Buddhist practices, and disaster aversion strategies amongst airport workers in Myanmar and Thailand, is that some flight attendants would plan their flight schedules to avoid working on Friday the 13th. Interestingly, every culture has its own set of lucky and unlucky days and associations. For instance, as ANU's Associate Professor of Anthropology, Matt Tomlinson cites, in Latin American culture, it's Tuesday the 13th that's considered unlucky instead.
