User blog comment:VoodooVinceFano3o/Why do people think that the bite in fnaf 4 took place in 1983?!/@comment-26572957-20150811114746

It has to be set in 1987 because Phone Guy never explained about anything bad in 1983.

Also when Phone Guy described about the Bite of 87, the location the bite was at may of been a Sister Location which was set at the same time of FNaF2.

As ******** Caused the Bite of 87, not in 83.
