Day

Day is the time when the sun comes out. Most The Legend of Zelda series games exclusively take place in daylight, but the 3D games in particular make use of the change between day and night as a game mechanic.

Appearances as a game mechanic

Ocarina of Time

While A Link to the Past had its opening sequence take place at night, Ocarina of Time is the first game to have a rotating day/night sequence. Time passes only when Link is in open areas such as Hyrule Field - towns and some other areas remain in the day/night state where Link enters them.

Certain NPCs, Mini-Games and Shops are available only during daytime.^{[Which ones?]}

Link can change day to night and vice-versa by playing the Sun's Song, written by the Composer Brothers.

Skyward Sword

Time does not pass, and day is the only state of most areas in the game. In The Sky only, Link can change day to night and vice-versa by sleeping in a bed.
