We live in a time when unmanned spacecrafts are discovering water on Mars, and police are pulling over self-driving cars. A time when the pace of technological and scientific advancements move at a lightning-quick pace.

And yet we’re hard-pressed to let a Friday the 13th go by without some type of acknowledgement of its “bad luck” devilry. It’s as if we’re afraid that those same invisible forces piloting our spaceships and automobiles will rain down torrents of misfortune if we don’t respect that date’s supernatural authority. Maybe we should blame Jason Voorhees.

Since humankind began ordering and marking the days of the week, cultures around the world have been preoccupied with “unlucky” days. Usually, those dates are associated with an historical event so monstrous that its wickedness continues to echo through the ages. Occasionally, superstitions around numerology have something to do with their bad vibes. Friday the 13th is one of those dates that has its bad luck rooted in both: It mixes Jesus’ last supper and crucifixion with our general mistrust of the number 13.

But Friday the 13th hasn’t cornered the global market on bad luck days. Here are a few more cursed dates that have been recognized around the world over time.

1. Tuesday the 13th

This almost sounds like the title of a bad horror movie parody starring either Leslie Nielsen or the Wayans brothers. Actually, it’s the go-to bad luck date for Greece, as well as many Spanish-speaking countries, something Reddit user jeihkeih discovered and posted about in the Today I Learned community. Why the move on the calendar to an early day in the week? Blame it on the day’s association with Ares, the Greek god of war, as well as the sieges of Constantinople in the 13th and 15th centuries, which both happened on Tuesdays. Because if you’re going to plan a siege, Tuesday is really your ideal day.

2. Friday the 17th

In Italy, Friday’s association with Jesus’ death still generates some mean mojo. But you have to do a little work to find the source for all the agitation over this date. The number 17 is XVII in Roman numerals, and those characters can be rearranged to spell “vixi,” which means “I have lived” in Latin. That’s considered unfortunate phrasing—it indicates that you’re dead right now—that augurs bad things.

3. Aug. 15

The rokuyō is an Asian calendar system that identifies the six lucky and unlucky days in a year. Guess which category this date falls in? Representing the day Buddha died, Aug. 15—known as butsumetsu—is considered to be a terrible, no good, very bad day in Japanese culture, and couples are advised to avoid being married on that day.

4. Dec. 28

This date—which is known as Innocents’ Day, the Holy Innocents’ Day, and Childermas—marks Herod’s cull of Bethlehem’s male children in hopes of slaying the newborn Jesus. Because it’s a bit unseemly to get too cheery on the anniversary of a massacre of children, the day has a long association with being unlucky. Like Japan’s Aug. 15, couples avoided being married on that date. France’s King Louis XI wouldn’t conduct business on Dec. 28 during his reign, and England’s King Edward IV moved his coronation a day later to Dec. 29 to avoid any chance of his monarchy being tainted by bad luck.

Other cultures, however, have a more charitable view of Dec. 28. In Mexico, it’s the equivalent of April Fools’ Day, and in Belgium, children pull pranks on adults on this day.

5. A Reason to Hate Mondays

Often, fatherly advice can provide practical guidance for a child as he or she matures into adulthood. Other times, it can be downright ridiculous. In the late 16th century, William Cecil, Lord Burghley, an adviser to Queen Elizabeth, wrote down some final words of wisdom for his son before the baron shook off this mortal coil. One nugget Lord Burghley passed along was a warning to beware what he did on these three days each year:

the first Monday in April, the day Cain was born, as well as the day he killed his brother Abel

the second Monday in August, the day Sodom and Gommorah were destroyed

the last Monday in December, the day Judas was born

It’s unclear if Lord Burghley was the first person to be diagnosed with a case of the Mondays.
