Origin
As a youth, Julian Day's father promised he would be home for the holidays. Taking a bus to wait for him at a bus stop, Day waited from Christmas Eve to New Year's Day. When the police took Day in on New Year's Day, he was almost dead from exposure. From then on, Day began to assign almost literal meanings to each day. In addition, he began to suffer mood swings related to the days.

Within a few months, Mother's Day came but Julian's mother wasn't exactly the warmest person to approach. Julian tried to demonstrate his love but his mother showed nothing but contempt with her cold dead eyes. In a fit of uncontrollable rage, Julian attacked his mother. When Julian regained his senses, he realized that he was holding his mother' beating heart in the bloody palm of his hand.

On Father's Day, Julian discovered that his old man was living in East End Docks. Julian tells his father that he wants to clear the air between them by having an afternoon to themselves. Julian insists that the two of them go out onto Gotham Bay for some fishing. The day slowed to a crawl as Julian finished hacking what was left of his father. Julian used various parts of his father to reel in some big catches. From that day forward, when ever Julian ate a nice serving of fish, he felt a little bit closer to his dear old dad.
