Opening Boku's Diary from the menu of a completed save file and continuing to the next day via a glitched button prompt will cause the game to continue past its end point and into August 32nd.

This date has no associated data in the files, but the game continues from one non-existent day to the next without crashing, instead inciting a series of glitches that affect where the player can go, the legibility of text onscreen, and what textures are applied to the character models.
