There are many theory’s of when FNAF 1 takes place, but personally, I think 1993. In the paycheck in FNAF, it shows that the date is Friday, November 12. The years that Nov. 12 is a Friday is 1982, 1993, and 2004. Out of all of these, 1993 makes the most sense. Credits to RyeDoze for most of the information.
