Nothing will take place on Friday, December 30, 2011 in Samoa. Historical records will not exist. Newspaper entries will not record the comings and goings of Samoans on December 30. The Samoans have collectively decided to give the day a miss. They are going to sleep on Thursday, and waking on Saturday. If you are reading this at work, one of the few people in the office, you're probably wondering why you didn't give Friday a miss as well.
If you cannot immediately conjure a mental of image of Samoa, imagine an island nation straddling the international dateline on the wrong side of their largest trading partners, Australia and New Zealand, which limits Samoans to only 4 shopping days per week.
Someone had the bright idea of paying the International Map Line Drawers Association to move the date line a tad to the east so Samoans and their friends would all be on the same day. American Samoa took a pass. They apparently like Fridays.
