Calendar Man

Calendar Man (Julian Gregory Day) is a supervillain appearing in American comic books published by DC Comics, as an enemy of the superhero Batman, belonging to the collective of adversaries that make up Batman's rogues gallery. Calendar Man is known for committing crimes that correspond with holidays and significant dates. He often wears costumes to correlate with the date of the designated crime. His name, in itself, is a joke, referencing both the Julian and Gregorian calendars. In his debut, the character was presented as a joke villain, but in later years, writers developed Calendar Man as a dark, disturbed serial killer who toys with Batman. The character made his live-action debut as a cameo in the DC Extended Universe film The Suicide Squad (2021), portrayed by Sean Gunn. Publication history Calendar Man first appeared in Detective Comics #259 (September 1958) and was created by Bill Finger and Sheldon Moldoff. He returned after twenty years to plague Batman again in Batman #312 (June 1979). Fictional character biography
