Adoption History & Astronomical Facts
Year Established: 1931
Adopted by supreme decree in 1931 to anchor standard time to the 60th meridian west. An experimental summer daylight shift was briefly attempted from October 1931 to March 1932, but proved unnecessary due to negligible seasonal shift in sunrise times.
At 3,640 meters above sea level, La Paz is the world's highest administrative capital. It operates on the same UTC-4 offset as Caribbean sea-level islands like Puerto Rico and Barbados.
