This is the very first Day at the start of the game. No doors have been locked (excluding the Door between the Dining Room and the Backyard, and the door between the Jail Cell and the Baby Room; as these Doors are always locked and only Granny can open them). The Player does not appear to be injured at all, despite the fact that the Player was most likely hit by Granny's bat and was dragged into the Starting Bedroom before the events of the game (as seen in the PC version).
If the Player gets to Day 2, they will find that they wake up with a slight limp. They will also find that the Door to the Starting Bedroom has been locked by Granny. In order to leave their room, the Player must lure her into opening the Door by making noise, whether it be by knocking the Table over, dropping the Vase on the floor, or knocking over the Painting. She will rush upstairs and unlock the Door to investigate, leaving it unlocked after she leaves.
The Player's limp has gotten more noticeable. The Door connecting the Main Room and Bedroom 2 is now locked in its place and will stay locked through all future days until Granny is lured into unlocking it.
This is the last day you have to escape unless you unlock the Bonus Day. Otherwise, if you get caught, you will get a Game Over.
