History
Tonga has been on UTC+13:00 for many years. Daylight saving time was used in the southern summer seasons from October 1999 to January 2002, and from November 2016 to January 2017.
UTC+13:00 was used until 2009 as a daylight time in the easternmost parts of Russia that used Kamchatka Time.
At the end of , Samoa advanced its standard time from UTC−11:00 to UTC+13:00, essentially moving the international date line to the other side of the country, skipping. Following Samoa's decision, Tokelau also simultaneously advanced its standard time, from UTC−11:00 to UTC+13:00.
Fiji, where normal time is UTC+12:00, decides year by year whether it will observe DST, and if so for which dates, which are usually a short period between November or December and January. No DST has been observed since 2020–2021.
