Well I didn’t realize today is Friday the 13th until I saw an Email mention of Friday the 13th.
Friday the 13th occurs when the thirteenth day of a month falls on a Friday, which superstition holds to be a day of bad luck. In the Gregorian calendar, this day occurs at least once, but at most three times a year. Any month’s 13th day will fall on a Friday if the month starts on a Sunday.
When I first heard of Friday the 13th back in the days when I first arrived in America back in the late 80s, I actually believe it, I guess when you’re kids you believe in many things, until later it doesn’t really appeal to you anymore or doesn’t seems to make sense because we get smarter 🙂
The fear of Friday the 13th is called friggatriskaidekaphobia (Frigga being the name of the Norse goddess for whom “Friday” is named and triskaidekaphobia meaning fear of the number thirteen), or paraskevidekatriaphobia a concatenation of the Greek words Paraskeví (Παρασκευή, meaning “Friday”), and dekatreís (δεκατρείς, meaning “thirteen”) attached to phobía (φοβία, from phóbos, φόβος, meaning “fear”). The latter word was derived in 1911 and first appeared in a mainstream source in 1953.
