when was the last time a president declared a national day of prayer
National Day of Prayer Republican President Donald Trump and First Lady Melania Trump attended church services in observation of a special National Day of Prayer, which Trump previously declared, in support of the victims of Hurricane Harvey dwelling in the state of Texas, to "uplift one another and assist those suffering from the consequences of this terrible storm."[32][33]
Memorial Day The preferred name for the holiday gradually changed from "Decoration Day" to "Memorial Day," which was first used in 1882.[47] 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.[48] 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.[49] 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.[49] After some initial confusion and unwillingness to comply, all 50 states adopted Congress' change of date within a few years.
