Events that disrupt usual routines are always a bit scary. Hence the precautions and the reluctance to do anything really important like starting a new business, especially on February 29th. “Nothing shall be built, planned or planted in a leap year; it does not prosper,” states the “Encyclopedia of Superstitions, Folklore and the Occult Sciences of the World.”
In many countries around the world, superstitions claim that bad luck will come to couples that marry during a leap year. Yet, according to a popularized legend, St. Patrick granted to St. Bridget the right for all single women to propose marriage during leap years. And any man who refuses a woman’s proposal on February 29th has to compensate her by buying 12 pairs of gloves or a skirt.
So perhaps a leap year is a good year if you think different and exceed expectations? As Steve Jobs said, "the ones who are crazy enough to think that they can change the world, are the ones who do."
