If you’ve been fortunate enough to play the “untouchable” Batman: Arkham City, then you’ve no doubt witnessed all the branching story lines in the game.  One such semi-story is that of Calendar Man.  His story is perhaps the most interesting because it involves a really unique Achievement called “Story Teller”.  When you visit Calendar Man inside Solomon’s Courthouse, you’ll see a calendar of sorts with a series of circled dates.

If you talk to Calendar Man on each of these dates, you’ll get the Achievement.  It’ll take a long time to get this Achievement if you don’t cheat with your system clock of course.  It’s very clever of Rocksteady to do though for those of you who are playing it straight.

Today is one of the days on the calendar so go talk to him and start the journey.  There’s a day in each month until next September.
