The same day, their mirror at home fell and broke, which, according to superstition, leads to 7 years of bad luck. Some say that the concept of Friday and the number 13 being unlucky may be linked to stories from the Bible.

For example, Judas Iscariot, the apostle who betrayed Jesus, has been labeled "the 13th guest" at the Last Supper. Other biblical events that supposedly occurred on a Friday include the great flood during the time of Noah, the confusion of languages at the Tower of Babel, the day Eve tempted Adam with the apple, and Good Friday , the day Jesus was crucified.

On Friday 13, October , a warrant was issued for the Knights Templar to be arrested. Masses of Templars were tortured or executed. The superstition surrounding Friday 13 could also be linked to Norse mythology. According to one legend, 12 gods were at a banquet at Valhalla when Loki, the demi-god of mischief who was not invited, turned up, bringing the total number of guests to He was responsible for the chaos that led to the death of one of the good gods, Balder, so all the gods grieved.

The ancient Egyptians thought the number 13 was lucky because they believed that the 13th stage of life was related to the afterlife. After the decline of the ancient Egyptian civilization, the number 13 was still associated with the end of earthly life. However, its connotation shifted from hope to death and fear. Incidentally, if you memorize this string of numbers that represent the months — 0 3 3 6 1 4 6 2 5 0 3 5 — you can figure out the day of the week for any date using simple addition and casting out 7s.

You can do it pretty quickly in your head with some practice. For dates in the s use the number of years plus number of leap years since You are allowed to tamper with the monthly distribution of days in a normal nonleap year in the following way: You can take away one day from any month of the year and add it to any other.

Or you could, like a kleptocrat, decree that January has 32 days while poor February has just What if you could do the above procedure for two pairs of months, without using any month twice?

You can solve this by inspecting the string of numbers we obtained above: 0 3 3 6 1 4 6 2 5 0 3 5. There are already three 3s, so it is simplest to try to maximize them. Notice that there is a 4 and a 2, and we can convert both to 3s by performing the day-borrowing procedure described on adjacent months. By taking a day from May and giving it to June, we can surgically alter the 4 to a 3, thus adding a fourth 3 and potentially creating a fourth Friday the 13th.

Similarly, by borrowing a day from August and giving it to July, we can change the 2 to a fifth 3, without changing any of the other offsets. So our string of offsets is now 0 3 3 6 1 3 6 3 6 0 3 5, which includes five 3s.

Lucky you! Pete Winkler pointed out that the 13th is in fact more likely to be a Friday than any other day of the week, something, he said, that was proved by a year-old! Just knowing this fact, it is possible to conclude that there is an integral number of weeks in a time period of years. Do you see how? On the subject of days and dates, there is something special about the 12th of March, the 9th of May and the 11th of July that requires a global perspective to appreciate.
