Fan Casting Calendar Man in Return to the DC Universe

A brilliant mind, yet obsessed with dates, months, and holidays, Julian Day became insane from time in solitary confinement, which led him to take on the moniker of Calendar Man. His actions led him to base much of his crimes on his obsession, which led him to be locked up in Arkham Asylum. In the case of the Holiday Killer and the Hangman, Day was a help to Batman and his allies, though it also was of his own reasoning to not be forgotten. Now on the loose after Arkham's destruction, Calendar Man is biding his time for his next scheme.
