Unlucky Numbers Around the World: 13, 4, 17 and Their Stories

Have you ever avoided the number 13 or felt uneasy about the 4th floor? You're not alone. Around the world, certain numbers carry a heavy load of superstition—and their stories are fascinating.

Why We Fear Certain Numbers

Numbers are just symbols, right? Yet many people feel a real chill when they see 13, 4, or 17. This fear has a name: triskaidekaphobia (fear of 13), tetraphobia (fear of 4), and heptadecaphobia (fear of 17).

Why do we attach so much emotion to digits? It often starts with old stories, religious tales, or simple wordplay. For example, in some languages, the word for a number sounds like a word for death or suffering. Over time, these ideas spread through culture, movies, and even building designs.

Remember, these fears are not based on science. They are part of our shared human imagination. That's why we explore them here—for fun and curiosity, not as a guide to real-life luck.

The Infamous Number 13

The number 13 is the most famous unlucky number in Western culture. Many hotels skip the 13th floor, and some airplanes don't have row 13. Why all the fuss?

One popular story comes from the Bible. At the Last Supper, there were 13 guests, and the 13th was Judas, who betrayed Jesus. Another old tale from Norse mythology says that a dinner party with 13 gods led to trouble—Loki, the trickster, was the uninvited 13th guest and caused chaos.

Even today, some people avoid having 13 people at a table or starting a trip on the 13th. But here's the twist: in some cultures, 13 is actually lucky! For example, in Italy, 13 is often considered a lucky number, especially for gambling and love. So, the fear of 13 is not universal—it's just a story we tell in many places.

The Unlucky Number 4 in East Asia

In China, Japan, Korea, and other East Asian countries, the number 4 is often avoided. Why? Because in Chinese, the word for "four" (sì) sounds very similar to the word for "death" (sǐ). This similarity makes 4 feel like a bad omen.

You'll see this fear in daily life. Many buildings in these countries skip the 4th floor, just like Western buildings skip the 13th. Phone numbers, license plates, and even product prices may avoid the digit 4. Some hospitals don't have a 4th ward, and some families won't give gifts in sets of four.

But not everyone sees 4 as bad. In some contexts, like music, the number 4 can represent harmony and stability (think of a four-beat rhythm). So, like all number fears, it's about perspective.

Italy's Number 17

In Italy, the number 17 is considered very unlucky. Why? The Roman numeral for 17 is XVII. When you rearrange those letters, they can look like "VIXI," which in Latin means "I have lived." That phrase is often found on tombstones—it's a way of saying "my life is over." So, seeing 17 can feel like a reminder of death.

Because of this, many Italian buildings skip the 17th floor, and some airlines avoid seat 17. The fear is so strong that in some Italian lotteries, the number 17 is linked to bad luck. But remember, this is just a cultural belief, not a fact.

Interestingly, in other places, 17 is seen as a positive number. In some Asian cultures, 17 is associated with good fortune. So, numbers are like clothes—what's scary in one place might be stylish in another.

Other Unlucky Numbers Around the World

Beyond 13, 4, and 17, many other numbers carry negative meanings in different cultures.

• Number 9 – In Japan, 9 sounds like the word for "suffering" or "pain." Some hospitals avoid the 9th floor.
• Number 39 – In Afghanistan, 39 is seen as unlucky because it sounds like a phrase meaning "dead cow" or "prostitute." Many people avoid it.
• Number 666 – In Christian traditions, 666 is known as the "number of the beast" from the Book of Revelation. It's often linked to evil or the devil.
• Number 7 – Wait, 7 is usually lucky! But in some parts of China, 7 can be unlucky because it sounds like "to deceive" or "to cheat." Also, the seventh month is sometimes called the "ghost month."

These examples show how numbers get their meanings from language, religion, and history. It's all about stories, not science.
