Yes, that day is fast approaching — and it's the second of three this year. Are you the superstitious sort? Then these are just some of the things you might want to avoid! Warning: You might not want to leave the house after reading this.
1. Pass a funeral procession
Some believe that if you do, you might end up with some form of misfortune the next day.
2. Give birth
The child might come across bad luck for the rest of his/her life.
3. Change the bedsheets
You risk having bad dreams.
4. Cut your hair
You might end up "snipping" the life of a family member.
5. Cut your nails
You might experience more bad luck for the rest of the year.
6. Start a new job or open a business
Naysayers could tell you that it will eventually collapse or become bankrupt. Black Friday has been associated with stock market crashes and other disasters since the 1800s.
7. Begin a trip
Problems might crop up. The most famous example of unlucky 13 is the Apollo 13 mission. It was launched at 13.13 hours and was aborted on April 13.
8. Embark on a sailing trip
Like the one about travelling, ships should think twice before leaving the harbour this day.
9. Consult a fortune teller
You might not like the news you hear. Also, going to see an astrologer on a "13" day goes against the principles of astrology. Think about it: There are just 12 zodiac signs and 12 months in a year.
10. Leave your calendar on the day marked Friday the 13th
You might end up with tons of bad luck. According to legend, the Norse goddess Frey (Friday) came down to Earth and gave a coven of witches her cat. Covens usually gather in groups of 12, but the addition of Frey's cat made the coven 13. Some believe that the 13th coven member was actually the devil!
