For the last time I'm sorry, Debbie. Come on, I know it's June-ish.— Calendar Man

Julian Day (aka Calendar Man) is a supervillain obsessed with committing crimes on holidays and specific dates, but he just can't remember his own son's birthday. However, despite this he’s getting there because he remembers that it’s June-ish.

He was an inmate at Arkham Asylum with Harley Quinn and Poison Ivy before Ivy staged an escape. While incarcerated alongside them, he kept track of how many days Harley had been there. He is later seen to have escaped and being a part of the Legion of Doom

  • His head marked with calendar months are similar to the Batman: Arkham Asylum game series.
  • This version of Calendar Man seems to be a combination of the gimmicky costume version and the more serious serial killer version.
