when did memorial day changed from may 30th
Memorial Day The preferred name for the holiday gradually changed from "Decoration Day" to "Memorial Day," which was first used in 1882.[61] Memorial Day did not become the more common name until after World War II, and was not declared the official name by Federal law until 1967.[62] On June 28, 1968, Congress passed the Uniform Monday Holiday Act, which moved four holidays, including Memorial Day, from their traditional dates to a specified Monday in order to create a convenient three-day weekend.[63] The change moved Memorial Day from its traditional May 30 date to the last Monday in May. The law took effect at the federal level in 1971.[63] After some initial confusion and unwillingness to comply, all 50 states adopted Congress' change of date within a few years.
