Day and night cycle

The day and night cycle is a recurring feature in some of the newer games in the Final Fantasy series. It features an ongoing time on depending on it, day and night will cycle. Typically, each location has different themes for different times, and at times the specific location's battle theme may change as well.

Lightning Returns: Final Fantasy XIII
The aspect of the day and night cycle is important in Lightning Returns: Final Fantasy XIII since it ties closely to the game's story. Many main and side quests are dependent on the current time. Also, Lightning has a limit of thirteen days for her to complete all main quests in order to advance to the last day where the aspect of the ongoing day and night cycle ceases to exist.

There are four times of day present in the game and on each a different field and battle theme will play, although some areas are exempt from this rule:
 * Morning: 6:00 - 11:59.
 * Afternoon: 12:00 - 17:59.
 * Evening: 18:00 - 19:59.
 * Night: 20:00 - 6:00.
