UTC−12:00, Time zone in Baker and Howland Islands, United States
UTC−12:00 is the time zone for Baker and Howland Islands, two remote United States territories in the central Pacific Ocean. These islands sit at the far western edge of the International Date Line and are among the last places on Earth to reach each new calendar day.
The United States claimed these islands between the 19th and early 20th centuries and established this time zone for their administration. The time designation became standardized to define the position of these territories relative to Greenwich Mean Time.
This time zone serves as a reference point for global coordination, particularly in international date line calculations and worldwide temporal measurements.
These islands sit 12 hours behind Coordinated Universal Time and observe no daylight saving adjustments throughout the year. Visitors should know that these locations are extremely isolated and accessible only with careful planning.
These islands host scientific research stations where researchers monitor seabird colonies and marine ecosystems. The locations are so remote that only authorized expeditions gain access there.
