None. It is only about 1/10th of a day.
depending on how many days there areon the 13th month. if the 13th month would have 31 days i'd say ther'd be 396 days in a year oh and there would still be 60 seconds in a minute.if u ask how many seconds are in a year with thirteen months it would be 34,214,400 seconds in it i think? hope this helped...
