Friday 1st February 2008 - Disappears! On the east west leg of this back to back circumnavigation of the globe we crossed the IDL from east to west - thereby gaining a day. We had the same day twice. This time, crossing from west to east the 1st February did not exist! We went from 31 Jan to 2nd Feb. Still as all these days are sea days and pretty much the same it didn't really matter.
