Convert time from Kwajalein
Kwajalein is a long, thin atoll enclosing one of the world’s largest lagoons, and it hosts the Ronald Reagan Ballistic Missile Defense Test Site, a US Army facility that has tracked missile tests across the Pacific since the Cold War. The atoll runs on Pacific/Majuro time: UTC+12, year-round, no daylight saving.
missile range, WWII wrecks, and two clocks on one atoll
In 1993, Kwajalein Atoll advanced from UTC-12 to UTC+12, skipping an entire calendar day (August 21, 1993), to align with the rest of the Marshall Islands. Before that, Kwajalein had been operating at UTC-12, the furthest-behind timezone on earth, while the rest of the Marshall Islands were already at UTC+12. The change aligned the atoll with its main trading partners in Asia and Australia.
The US military presence on Kwajalein operates partly on its own schedule, tied to missile test windows and coordination with mainland US facilities. The military base time has historically been kept separate from the Marshall Islands civil time, creating a miniature two-clock situation within the atoll.
The lagoon at Kwajalein is one of the world’s premier wreck diving sites, with dozens of Japanese vessels sunk during the US assault of February 1944. The wrecks rest in shallow, clear water, undisturbed in the atoll’s protected depths.
9am in Kwajalein is 9pm in London the previous evening, twelve hours ahead.
