What is Prayer Day Holiday ?

The National Day of Prayeris an annual day of observance held on the first Thursday of May, designated by the United States Congress, when people are asked "to turn to God in prayer and meditation". Each year since its inception, the president has signed a proclamation, encouraging all Americans to pray on this day. The modern law formalizing its annual observance was enacted in 1952, although it has historical origins to a mandate by George Washington, the first president of the United States. On the National Day of Prayer, Americans from many religious backgrounds turn to God in prayer for the United States. Its constitutionality was unsuccessfully challenged in court by the Freedom From Religion Foundation after their first attempt was unanimously dismissed by a federal appellate court in April 201
