UTC+12:00 (Marshall Islands Time)

UTC+12:00 is shared by several Pacific Island nations and is one of the world's latest timezones (before DST adjustments push some to UTC+13 or even UTC+14). The Marshall Islands, Fiji (standard time), Nauru, Tuvalu, Wake Island, and New Zealand all use UTC+12 as their base offset. The Marshall Islands, a nation of 29 coral atolls and 5 islands, uses this offset year-round. Majuro, the capital, is the political and economic center. The Marshallese have been expert oceanic navigators for thousands of years, using stick charts (mattang) to map wave patterns and currents. The islands were the site of extensive US nuclear testing from 1946-1958, including the Castle Bravo test on Bikini Atoll, the largest US nuclear detonation. The Compact of Free Association gives Marshallese citizens the right to live and work in the United States. UTC+12 positions these nations at the International Date Line, meaning they are among the first to begin each calendar day. The timezone's position at the eastern edge of the date line creates interesting scenarios during New Year celebrations, as midnight arrives here hours before most of the world. The IANA designation 'Etc/GMT-12' uses the counterintuitive POSIX sign convention where minus means east.
