INTERNATIONAL DATELINE 
The International Date Line sits on the 180º line of longitude in the middle of the Pacific Ocean, and is the imaginary line that separates two consecutive calendar days. It is not a perfectly straight line and has been moved slightly over the years to accommodate needs (or requests) of varied countries in the Pacific Ocean. Note how it bends to include all of Kiribati, Samoa, Tonga and Tokelau in the Eastern Hemisphere. 

Immediately to the left of the International Date Line the date is always one day ahead of the date (or day) immediately to the right of the International Date Line in the Western Hemisphere. 

On the time and date codes shown below, note thatTonga and American Samoa have the same time but are one day apart, as American Samoa is in the Western Hemisphere, on the opposite side of the International Dateline from Tonga. A global Earth view is here. 

As you travel further west, note that the time in Fijiis one hour earlier than Tonga. You will also notice that Hawaii, further to the east of American Samoa, is one hour later in time. 

So, travel east across the International Date Line results in a day, or 24 hours, being subtracted. Travel west across the International Date Line results in a day being added.

On December 31st, 2011, Samoa caught up with the world and cheated time itself by erasing 24hours from their calender. December 30, 2011, did not exist in Samoa. (1)

The implications for Samoans is a transitional dateline shift west of the dateline inline with Tonga which was, hitherto, the premiere nation in the world to welome in the new year. Now, the Samoans, are finally on the same side of the dateline as Tonga. The age old jeers and jibes by the Tongans of the Samoans being the last place on earth in literal time, has become nullified. Samoans have adopted the Caesarian prerogative and would change time and the Gregorian Calender to suit the Samoans.

Julius Caesar had created the modern Julian Calender which was accepted until the 16th century whence thePope Gregory XIII changed the course of time in line with the Roman Catholic Christian calender. The affront to a Roman Caesar can not be assuaged as the new Roman Caesar under the guise of a Pope and ahead of the Roman Catholic church would denigrate the Imperial Pax Romana and would repeal the Julian Calender for the Gregorian Calender.  (2)

The Samoans have felt compelled to be inspired by the Gregorian precedence and would amend the Gregorian Calender even further to suit their own grandiose designs. Henceforth, the Caesarian prerogative of the Samoan has been decreed and so shall come to pass, Samoa will change time itself. The audacity of the Samoans to change the dateline and to change time itself there is no other global power that can surpass this feat now and, perhaps, forever.
