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 is a reference to 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 criminal who toys with Batman. Calendar Man appeared in Batman: The Brave and the Bold, where he was voiced by Jim Piddock, and the Batman: Arkham series, where he was voiced by Maurice LaMarche. The character made his live-action debut in the DC Extended Universe film The Suicide Squad, portrayed by Sean Gunn.
