Jack Frost is the Public Domain Anthropomorphic Personification of cold in the air and the frost designs on windows. Unlike many, he is not necessarily associated with a holiday; although naturally he tends to be most active in Winter simply because that's where the action is. He can be depicted as playful and mischievous as a snow day; or as cruel as the killing ice.
