Calendar Man is an antagonist in ''Batman: Shadow War. ''He is a serial killer who timed and tied his crimes and murders thematically to certain holidays throughout a year.

Yearly Killing Spree
After being manipulated by the Riddler (who was posing as a psychiatrist) to surrender to his dark passions and become a serial killer despite Julian attempting to seek help for his mental issues, he decided to base his murders and crimes around holiday dates.

Julian's heinous crimes included stalking and murdering a couple on Valentine's Day, poisoning a beer keg at a party on St. Patrick's Day which led to numerous deaths, murdered his parents on their respective parent days and rigged fireworks on Independence Day which killed many people in a chain reaction. With the Riddler's help (who used Calendar Man as a distraction to execute his escape from Arkham), Batman managed to track him down on Halloween when he killed a scientist to steal a supersonic weapon that would kill anyone in earshot of it and tried to murder everyone at a Halloween party with the device, disguised with a demon mask while doing so however Batman stopped and captured him. In the police interrogation room, Calendar Man revealed the Riddler's part but not before he executed his break from Arkham. Calendar Man was incarcerated at Blackgate Penitentiary for his crimes and scheduled to die on Christmas Day.

Imprisonment
Calendar Man was quiet while he spent his time in prison and apparently did nothing but think however he still kept to his killer instinct on holidays, making him one of the most dangerous inmates in Blackgate. On Thanksgiving, Calendar Man gruesomely murdered an inmate and had ate his corpse like a cannibal.

Christmas Day
On Christmas Day, Calendar Man was expected to be executed via gas chamber for the murders he had committed. However, Dr. Harleen Quinzel saved the man's life when she psychologically analyzed him and officially declared him insane despite Warden Martin Joseph trying to convince her to change her diagnosis so he could be sentenced to death by Judge Harkness. Calendar Man escaped Blackgate when a prison riot was instigated by Bane, then he went on to murder Harkness by hanging him in revenge however was recaptured by Batman and Robin. Due to now being declared insane, his execution was commuted and was not fit to stand trial so he was re-imprisoned at Arkham Asylum.
