The concept of leap year and February 29th fascinated me when I was young. It was like some hidden room in a old haunted house or a hidden floor in a tall building. It was unfathomable that we would have a day just appear every four years, like magic. Strangely enough, I connect leap day with one of my childhood terrors. The ancient terror of England known as Spring Heeled Jack!
As a child, my mind easily reasoned that Spring Heeled Jack MUST be associated with leap year/day. Those that are not familiar with this nightmare from my childhood, take note. Jack terrorized England from 1837 to 1904 (his last reported sighting).
He was always described, by countless witnesses, as being a tall gaunt man, covered in what looked like a black oil suit (scuba suit?) and high boots, with hands covered in metal curved claws. He was reported to be able to vomit blue/green flames, had piercing green eyes, and very devilish look (small horns, and pointy features on his face). He had a penchant for attacking woman, trying to kiss their faces and tear off their clothes. Those unlucky enough to be attacked would describe his hands as "unearthly cold and clammy" and describe a smell of "burning cinders and sulphur". His most notable feature, and that which he gleaned his nickname, was his ability to jump great heights and distances. It was reported by a local police constable to have seen Spring Heeled Jack leap away from an attacked woman when perused and clear a 9 foot wall with ease.
As a child, I was absolutely terrified by this demonic, leaping villain. There are so many documented cases and stories about this creature, you should read at least one. I guess it was not hard for my young mind to connect that Spring Heeled Jack must come around every "Leap" year.
Hope everybody has a great hump/leap day! Hopefully you will not run into any sinister leaping creatures.
