Before a player untaps their permanents during the untap step, the game checks to see if the day/night designation should change.

Permanents with daybound and nightbound can't transform via any means other than their daybound and nightbound abilities. Notably, older cards such as Moonmist that instruct a player to transform permanents don't affect permanents with daybound or nightbound.

If it is night, permanents with daybound that enter the battlefield without being cast will enter with their nightbound faces up.
