The Final Day, sometimes known as the Third Day, is a playable period in Majora's Mask, starting at 6 in the morning one day before the Carnival of Time and ending at 6 in the morning of the day of the Carnival. Due the time system in the game, there is a great amount of events that only occur this day.
- Like the other days, the Final Day has its own unique version of the Clock Town theme that plays. At night there is no music until 12 PM, where the song "Last Hours'" plays instead.
- If it was not exploded in the days before, the giant rock blocking the access to the ranch will be gone.
- If Link has not completed their past sidequests, both Romani and Cremia will contemplate the Moon. If completed, they will have a conversation about being an adult. Anju's family stays inside their house, except Anju herself, who is waiting in Clock Town.
