Calendar Man is a criminal who commits crimes based off of different holidays on the calendar.
At some point before the Joker's attack on Superman, Calendar Man was incarcerated in Arkham Asylum. However, following Superman's institution of a new regime against crime, Calendar Man was broken out of prison, only to be recaptured and taken to an even more secure facility soon after.
One Year after the fall of Superman's Regime, Calendar Man was forced to join Amanda Waller's Suicide Squad. However, Waller was killed by a Batman impersonator, who forced the squad to work for his mysterious employer. Killing off every member the employer didn't find useful, Calendar Man was supposed to have his head exploded but the bomb that was implanted inside of him when he joined the squad malfunctioned, allowing him to survive another day.
