Birthday Superstitions Around the World: Why Do Some People Avoid Celebrating on Friday the 13th?

Friday the 13th is widely considered unlucky in many cultures, leading some people to avoid celebrating birthdays on this date due to superstitions about bad luck, misfortune, or negative energy. These beliefs have deep historical roots and vary significantly around the world, influencing how—and even if—people celebrate their birthdays when the date falls on this famously ominous day.

Why Is Friday the 13th Considered Unlucky?

The superstition surrounding Friday the 13th is strongest in Western cultures, where both the number 13 and the day Friday have long held associations with bad luck. When these two come together, it’s believed to amplify misfortune. This fear is so widespread that it even has a name: paraskevidekatriaphobia (fear of Friday the 13th).

Historically, the number 13 was seen as irregular and unbalanced compared to the "perfect" number 12 (12 months, 12 zodiac signs, etc.). In Christianity, Friday is linked with the crucifixion of Jesus, further deepening its unlucky reputation. Over time, these beliefs merged, and Friday the 13th became a date to avoid for important events—including birthdays.

Birthday Superstitions: How Friday the 13th Shapes Celebrations

Many families and individuals choose to reschedule or downplay birthday celebrations if their special day falls on Friday the 13th. Here’s how this plays out in practice:

• Rescheduling Parties: Some people move parties to the day before or after to sidestep bad luck.
• Low-Key Celebrations: Others opt for private, more subdued gatherings to "avoid tempting fate."
• Skipping Gifts: In rare cases, gifts or major purchases are postponed to another date.
• Protective Rituals: Certain families add lucky charms or rituals, such as lighting a specific number of candles, to "counteract" the date’s reputation.
• Online Tools: Some use a birthday countdown to plan festivities on an alternative date.

Despite these superstitions, many people embrace the date, using it as an opportunity for unique, memorable parties—sometimes with a spooky or playful twist.

Global Birthday Superstitions: A Cultural Comparison

Superstitions about birthdays—and unlucky dates—vary dramatically worldwide. Here’s a look at how different regions view Friday the 13th and other superstitions:

• United States & United Kingdom: Friday the 13th is the most infamous "unlucky birthday" date, with millions avoiding major events. Hotels often skip the 13th floor, and party venues may see fewer bookings.
• Italy: 13 is actually lucky! Italians consider Friday the 17th unlucky instead, so Friday the 13th birthdays are not feared.
• China: The number 4 (“si”) is considered unlucky because it sounds like the word for "death." Birthdays on the 4th or 14th may be quietly skipped.
• Japan: Similar to China, 4 and 9 are avoided. Some people won’t celebrate 42nd birthdays due to its association with "death."
• Greece: Tuesday the 13th is considered unlucky, not Friday the 13th. Birthdays falling on this day may be rescheduled.
• Latin America: Tuesday the 13th is unlucky in Spain and many Spanish-speaking countries, so Friday the 13th holds less weight.
• Russia: Some Russians avoid birthdays before the actual date, believing it brings bad luck. Friday the 13th is less noted.

This variety shows how birthday superstitions are shaped by local beliefs and language. You can explore more birthday traditions and etiquette in our guides hub.

5+ Common Birthday Superstitions (and What to Do About Them)

• Never Wish Happy Birthday Early: In many cultures, early wishes are thought to bring misfortune to the birthday person.
• Blowing Out All the Candles: If you blow out every candle in one breath, your wish will come true; if not, it won’t—or so the superstition goes.
• No Sharp Objects as Gifts: Giving knives or scissors is said to "cut" the relationship.
• Even vs. Odd Numbers: In Russia and some Eastern European countries, an even number of flowers at a birthday is for funerals, so always give an odd number.
• Lucky Colors and Numbers: In China, red is lucky, and so is the number 8. For a birthday, avoid unlucky colors or numbers in décor and gifts.
• Friday the 13th Parties: Some people turn superstition on its head, hosting themed parties with black cats, ladders, and "unlucky" games for fun and novelty.

Superstition vs. Science: Does Friday the 13th Really Matter?

Despite the persistent myths, there’s no scientific evidence that Friday the 13th is any unluckier than other days. Studies on accident rates and hospital admissions have found little difference between Friday the 13th and other Fridays. However, belief in bad luck can have a real psychological impact: people may feel more anxious, cautious, or even avoidant on this date, which can subtly shape their birthday experience.

If the date worries you, focus on what makes the day special, not the number. Use a birthday countdown to look forward to your celebration, or try a fun wish from our wish generator to start the day on a positive note.
