Everyday Einstein – 8.13.2010

We hope you don’t have triskaidekaphobia. Here’s a puzzle about Friday the 13th:

“Luis was very superstitious and thought that Friday the 13th was bad luck. He and his friend Nathan had a big disagreement. Nathan said that it was only possible to have one possible Friday the 13th in a year and Luis said that he was certain there could be more then one in a year. What is the greatest number of Friday the 13th’s that could occur in one year?”

Can anyone name a year this happened? Anyone name MORE THAN 1 year?
