Many Americans will be making use of the public holiday today to celebrate Labor Day. At some point, you'll want to take some time out of your day to put in a copy of Batman: Arkham City
to pay another visit to Calendar Man today, September 3rd. If you do so, he'll tell you a story and you can cross off another of those 12 murderous dates needed for the following achievement:
Calendar Man can be found in the basement of the Solomon Wayne Courthouse, to which you gain access near the beginning of the game. All you need to do is to talk to him on each of the 12 dates that are circled on the calendar outside his cell. Alternatively, you can also gain this achievement offline by changing the date on your console. If you're one of the people who want to actually visit Calendar Man on every date needed, the next date to remember will be October 31st.
There will be a few more date specific achievements popping up throughout September and we'll be sure to remind you about those nearer the time. You can either keep your eyes peeled to TA's front page for those articles, or subscribe to the Achievement Reminders news category
to receive PMs or e-mails every time we remind you about those achievements.
