Rocdocmac is close. You get one day for the 5 minutes, one day for crossing the international date line, and one day for a leap year.
So if you are east of the international date line at 11:59 on the 28th of February, then cross the line and wait a minute or so, it becomes the 2nd of March. On a subsequent leap year these dates could correspond to Sunday and Wednesday.
