Lightning Returns: Final Fantasy XIII days

The progression of Lightning Returns: Final Fantasy XIII is divided in days. A day lasts 24 in-game hours, but two hours in real time (time stands still in battles and in menus, during cut-scenes and while in the Ark). Depending on the day and time of the day, different events may happen: shops and venues may have opening times, some people are around only on certain days, Chaos Infusions appear at certain times, and storyline bosses' stats and form may change the later the player battles them in the game.

Day 5
Snow's stats change depending on which day player fights him: between days 1 to 5, he is encountered under the name "Snow Villiers" and his stats are standard.

Day 6
The boss encountered in the Dead Dunes changes depending on day: between days 1 to 6, Grendel will be the boss that Lightning and Fang battle,

Between days 1 to 6, Noel is encountered under the name "Noel Kreiss" and his stats are standard,

Day 7
If the player battles Noel from day 7 onwards, he is more powerful and encountered under the name "Noel Kreiss+".

Day 10
Between days 6 to 10, Snow is encountered under the name "Snow Villiers+" and has higher stats than "Snow Villiers".

Day 11
From 11th day onwards Snow is encountered under the name "Snow Villiers++" and his stats are higher than on "Snow Villiers+". If the player will fight long enough against Snow, he will transform into a half-Cie'th and lose his top rendering him topless and revealing muscles.
