Usually, this only affects a individuals, but for the entire island country of Samoa, they're going to go to bed on December 29 and wake up December 31! That's right, the entire country is skipping December 30th, 2011.
Why, you ask? Well, they've decided to switch to the other side of the international dateline. Back in 1892, the country which was originally located on the eastern side of the dateline, decided to align itself more closely with the United States, so the entire nation celebrated July 4, 1892, twice, placing itself on the western side of the line.
The area in red will skip December 30 to flip to the eastern side of the dateline.
Why the change? Well, these days Samoa now does much more trade with China, Australia and New Zealand than it does with the US and more of its tourists come from the Eastern Pacific now, so it only made sense.
Understandably, anytime you lose a day, you're going to make some people mad, so the government of Samoa decided to sweeten the deal, by declaring that employers will still need to pay workers for the Friday that never happened and that banks will be prohibited from charging an extra day's interest. Can Samoa handle it? I'm sure it can. The nation is no stranger to major change. Two years ago, they switched from driving on the left side to the right side of the road.
My recommendation is that our government follow Samoa's lead and forgo a day as well next year. Might I suggest skipping April 15? Anyone with me?
