The Seventh Day Adventist Church in Samoa issued a statement to clarify its position on the time zone change, which is happening at midnight on December 29, according to the Samoa Observer (No longer available online).
The planned realignment of Samoa to the western side of the date line was announced by Prime Minister Tuilaepa Sailele Malielegaoi and reported in the Associated Press on May 9, 2011. (A copy of the release was found on the abc News site, but it is no longer available.)
A statement on the SPD site makes this quixotical claim:
The sequence of days does not change. However in Samoa, because the government has decided to “change times and laws,” by dropping one day from the week, the names of those days will change. Consequently, the preparation day, which is still the sixth day of the week, will then be called Saturday; and the Sabbath day, the seventh day of the week will then be called Sunday; and the first day of the week will then be called Monday. Sunday-keepers will actually be worshipping with us on the true seventh day!
See the copy of Notice re International Date Line Act of 2011 on the Samoan Embassy site (PDF file). Does it change the names of the days of the week, or does it align the country with its original position in regards to the date line, which is the same as that of New Zealand and Australia?
