Just so we understand each other. The Calendar Man is being forgotten. I can't have that.

Julian Gregory Day, also known as the Calendar Man, is a supervillain from the DC Comics universe. He is an enemy of Batman. He is a criminal who is overly fixated on calendars, dates, and holidays and thus commits crimes themed around them, usually on the specific holidays.


Calendar Man is fascinated by dates and calendars. His crimes always have a relationship to the date that they are committed. The theme may be related to what day of the week it is or to a holiday or to a special anniversary on that date; he will plan his crime around that day. He often wears different costumes which correspond to the significance of the date, though he does have a main costume which has various numbers (meant to represent days on a calendar) sprouting from the shoulders.

After his first appearance, in which his crimes were based on the seasons of the year, his next appearance was in Batman #312 (June 1979), where his crimes were based on the days of the week, and his costumes reflected the Norse and Roman gods they were named for, i.e. Saturn.

The hunt for him proves dangerous for Batman considering a confrontation on Thursday led to him being hit with Calendar Man's ultrasonic sound weapon and almost killed, forcing him to convalesce in bed for days while the supervillain committed his Friday and Saturday crimes without serious opposition. On Sunday, knowing that the police would be waiting for him to attempt to steal an artifact of the Egyptian God of the Sun, Ra, he planned to leave the city instead on a train called the Western Sun Express. Fortunately, Batman realized this move and captured him at the train station before he boarded. This issue also marked the first appearance of his most commonly known "calendar cape" costume.

His next appearance in Batman #384-385 (June–July 1985) and Detective Comics #551 (June 1985), sees the Calendar Man at the onset of the Crisis being used as a pawn of the Monitor in an attempt to find someone to potentially eliminate the Batman for profit. In this instance, the Calendar Man's theme is holidays, and he attempts to use the young Jason Todd, as Robin, as the Batman's Achilles' heel with the promise of his demise on the first day of Spring, but it is ultimately Robin who is responsible for his defeat.

Calendar Man's crimes are generally petty and often ridiculous in nature with unnecessary flashiness. For instance, at the conclusion of Day's week spree, he took the time to needlessly change into his calendar cape costume at the train station even while Batman was in hot pursuit. As such, he is notorious among both heroes and villains alike for being something of a joke. Consequently, his post-Crisis appearances have been few and far between. He was once recruited by Killer Moth to form the villain team known as "The Misfits".

In Comic

Batman: The Long Halloween

His best-known latter day appearance is in the miniseries Batman: The Long Halloween, 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 Silence of the Lambs, 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, Batman: Dark Victory. In both stories, he is bitter that the new murderous rogues have taken the attention off him; Day fears that he is being forgotten. He is seriously harmed by Sofia Falcone near the end of Dark Victory, described as being barely alive and having his jaw broken.

Batman: Arkham Knight

Calendar Man appears in Batman: Arkham Knight comic. On Labor Day, Calendar Man murdered several people inside the Campbell Calendar Company. It was all just a plan to draw out Batman however. The Arkham Knight had given him Electrocutioner's gauntlets to disable Batman's communications. To Batman's great surprise, Calendar Man had gathered seven clones of Solomon Grundy, named after each day of the week, whom Calendar Man claimed to have created. Over the week it took Batman to defeat all of the creatures, Calendar Man had kidnapped a newborn baby. He then gave the exhausted Batman a list of names and told him that those people had been poisoned and had 24 hours to live. He instructed Batman to save them all and then return to him. If Batman failed to save all of the people on the list or brought any of his allies with him when he returned, Calendar Man would execute the baby. The listed citizens were saved but before Batman returned as ordered, Scarecrow visited Julian to dissuade him of his attempt to kill Batman. Grudgingly, Calendar Man relented and gave up the baby without a fight.

Before Knightfall Protocol that destroyed Wayne Manor and presumably killed the Batman was activated, Calendar Man could be seen hiding among the crowd, witnessing Batman's presumed death and fullfilling his vow that he would witness the whole life of the Dark Knight.





  • In The New Batman Adventures, the creators created a female version of Calendar Man, named Calendar Girl.
