Once every four years in the Gregorian Calendar, a day is added at the end of February to synchronize with the solar year. A leap year is any year with 366 days instead of the usual 365 days.

If you're superstitious, today is your day. It's Friday the 13th, and the first one of the year. You may be even more superstitious about a Friday the 13th in 2013, maybe a few too many 13s for you. So, how many more do we have this year?

Today, Friday the 13th, is unquestionably one of the most long lasting and best known superstitious days. People who are naturally superstitious will take steps to ward off its effects while those who aren't superstitious will sometimes attribute anything bad that happens to them on that day to it being Friday the 13th. But where did this superstition come from?

We have a banner year in 2012, with three Fridays the 13th, and today marks number two so far. We had our first Friday the 13th in January and our final one takes place in May. The maximum number you can have in one year is three, so we're pushing it to the max this year.
