Seems like it goes on until the "the right cosmological signs are observed," according to this book. Sounds like that could be a couple hours, or it could be days.

My guess, though, is that the signs they're looking for are the sort that occur every night, like certain stars appearing or something. The way it's described, it's the sort of thing you probably wouldn't want going on for more than one night.
