Until late 1994, the Republic of Kiribati was bisected down the middle by the 180th meridian (the International Date Line). While the capital in South Tarawa in the Gilbert Islands was celebrating Monday morning, the eastern Line Islands (including Kiritimati/Christmas Island) were still finishing Sunday afternoon.
The Nightmare of a Two-Day Working Week
The geopolitical arrangement was an administrative disaster for the developing island state. With its eastern territory 23 hours behind its western capital, government offices only shared four overlapping weekdays to conduct official communications. On Fridays in Tarawa, government offices in Kiritimati were closed for Thursday night; on Mondays in Tarawa, the eastern half was still observing Sunday church services.
To resolve this administrative impasse, President Teburoro Tito made an audacious proclamation: effective midnight on December 30, 1994, the eastern Line Islands and Phoenix Islands would eliminate December 31 entirely from their calendars and wake up straight into January 1, 1995.
Creating UTC+13 and UTC+14
By moving the Date Line over 3,000 km eastward into open ocean waters, Kiribati introduced two new time zones that had never formally existed before: the Phoenix Islands (UTC+13) and the Line Islands (UTC+14).
First into the New Millennium
As a direct consequence of this bold geographical redrawing, Kiritimati (Christmas Island) became the first inhabited territory to enter the new millennium on January 1, 2000. It remains the furthest-forward time zone in the world today.
Remarkably, Kiritimati shares the exact same clock hour as the state of Hawaii (e.g. 10:00 AM), but Kiritimati is an astonishing 24 hours ahead (a full calendar day) of Honolulu.
