His best-known modern appearance is in the miniseries ', where he is portrayed as a Hannibal Lecter-like figure, offering insight in Batman's search for Holiday, a serial killer who uses holidays as his "modus operandi". Like Lecter in the novels of Thomas Harris, Calendar Man knows who the killer is and keeps this information to himself, choosing instead to taunt the heroes with cryptic clues. He returns in that story's sequel, ', in which he impersonates deceased mobster Carmine Falcone in an effort to drive his children, Alberto and Mario, insane. When Calendar Man (as Carmine) tries to get Alberto to kill himself, however, the younger Falcone detects the ruse; Alberto knows that his father abhorred suicide, and thus figures out that Calendar Man is manipulating him. At the end of the story arc, Falcone's daughter Sofia Falcone Gigante beats him to a pulp as revenge for his role in her father's death. In both stories, Calendar Man is bitter that the new murderous rogues have taken the attention off him; he fears that he is being forgotten.
