According to Sant Nand Singh Ji if we can we should stay up at night and do Path if you stay up for as long as you can you get the merit(Is it the right word) as one amrit vela. If you stay uo the entire night and day you get the merit of a year worth of amrit vela. Sant Nand Singh Ji also said that Guru Nanak Dev Ji was born at 12:51 am. So if you are staying up at least stay up untill 12:51. If you are worried you will miss amrit vela you don't have to stay up at night. Just do simrin while sleeping.
