How long is a day in Dungeons and Dragons?

Answer 1

A day in DnD can last for as long or as short (in terms of actual time passed) as the DM wants it to. an in-game day can also last for as long or as short of a time as the DM wants it to be. the standard day on the prime material plane is usually 24 hours. (probably due more to laziness or apathy in the Dungeon design stage than any other factor. of course there is no standard time for the outer planes. again, there is no constant, you can make your in-game day as long as you want it to be, but sleep cycles are based on a 24 hour day. i hope i answered your question.
