Why is Friday the Thirteenth considered unlucky? 

While there is no definitive origin that can be pointed to as a reason why it is considered an unlucky day – but as noted above 13 is seen as an unlucky number while Friday was also considered unlucky in its own right. 

This again comes from Christianity as Friday was the day that Jesus was crucified and were seen as a day of penance and abstinence.

According to research it has been estimated that Friday the 13th costs businesses in America an estimated $800 or $900 million – because people are scared to take flights, go about their normal business or even leave their bed.
