Principal settlement: Kiritimati The central Pacific Republic of Kiribati introduced a change of date for its eastern half on 31 December 1994, from time zones UTC−11:00 and UTC−10:00 to UTC+13:00 and UTC+14:00.

As a British colony, Kiribati was centred in the Gilbert Islands, just west of the old date line.

Government offices on opposite sides of the line could only communicate by radio or telephone on the four days of the week when both sides experienced weekdays simultaneously.

The revision of Kiribati's time zone meant that the date line in effect moved eastwards to go around this country, so that the Line Islands, including the inhabited Kiritimati island, started the year 2000 on its territory before any other country on Earth, a feature the Kiribati government capitalized on as a potential tourist draw.

At the end of 29 December 2011 (UTC−10:00), Samoa advanced its standard time from UTC−11:00 to UTC+13:00 (and its daylight saving time from UTC−10:00 to UTC+14:00 until 4 April 2021), essentially moving the international date line to the other side of the country.
