Why is Friday the 13th unlucky? (English practice)

When a Friday falls on the 13th day of the month some people believe that this day will bring bad luck. They believe that this day has some special or magic power to cause bad things to happen.

*We use the expression fall on to mean a specific date will happen or occur on a certain day of the week.

This year my birthday (specific date) falls on a Saturday (Day of the week). Let’s have a big party!

This kind of belief is called a superstition in English.


superstition noun the belief that particular events happen in a way that cannot be explained by reason or science; the belief that particular events bring good or bad luck

“According to superstition, breaking a mirror brings bad luck.”

Where does this superstition come from?

Superstitions about the number 13 and Friday may have started in the Middle Ages. (The middle ages refers to a time in European history between the 5th and 15th centuries) 13 was considered unlucky for a long time.

The number 12 represents a complete cycle. 12 months in a year, 12 hours on a clock, 12 signs of the zodiac. 13 feels like 1 too many.

Both the number 13 and Friday were said to be unlucky, but it seems they weren’t combined into a single unlucky day (Friday the 13th) until the 19th century.

Several authors helped to spread the idea that Friday the 13th is an especially unlucky day in stories and books written in the 19th century. There are many legends and ideas about why we think of Friday the 13th as unlucky.
