Why Is 13 an Unlucky Number?

Many people believe that a Friday that falls on the thirteenth day of the month is an unlucky day. Have you ever wondered why? It’s easy, both Friday and the number 13 are considered unlucky.

The number 13 may be considered unlucky because there were 13 people, Christ and the 12 Apostles, present at the Last Supper. In some countries, it’s still considered unlucky to have 13 people at a table. There’s even a name for the fear of the number 13, triskaidekaphobia!

Friday has long been considered an unlucky day in many countries, although Muslims regard Friday as the holiest day of the week. The day may be unlucky because Christ died on Friday. According to the Bible, Adam and Eve were tempted by the serpent on a Friday, and the Great Flood of Noah’s time began on Friday. In some countries, Friday was the day for the execution of criminals.

In England, the government tried to prove how silly the superstition about Friday building a ship called the Friday. The ship was built starting on a Friday, and launched on a Friday. It sank on its first voyage!

  1. Friday is the luckiest day for me ever because when ever I receive my Results on friday, I will stand 1st in the class!

  2. i think 13 is an unlucky number is because do you know that theres 52 weeks in a year keep adding 52 x 13 = tell me the answer u get.

  3. I really cannot believe some of the replies here!

    The Knights Templar (you might want to check them out on google or something) were all arrested in co-ordinated attacks on Friday 13th October 1307

    It is from that that we all associate friday 13th as being unlucky

  4. to Logan,
    still not understanding where people get that thirteen is a number that is satanic, but the number 13 does seem to have people hype it up,now as to your math quiz, i hate math but i was interested in what it would be, so i did the first one was two 13s either way it would add to 13 and then the next that was sort of neat that the the question was the answer meaning 52 weeks in a year and the number 13 which i do not understand now to me if you take the numbers 666×2=you get 1332 which is the 333 but differently. those numbers the 6’s hold more meaning than the 13, because they the 666s are written about where 13 is not.
