Thanksgiving is essentially a harvest food festival, an annual celebration occurring during or shortly after the main harvest - a "thanksgiving" for the successful harvest observed primarily with feasting. In Britain, such festivals go back hundreds of years and are known today as Harvest Thanksgiving or the Harvest Festival of Thanksgiving. The worldwide influence of the United Kingdom spread this feasting tradition to countries around the globe.
Thanksgiving Day Parade
Two major, and equally famous, Thanksgiving Day parades occur in the United States on the same morning: America’s Thanksgiving Parade in Detroit, Michigan, which winds down historic Woodward Avenue and Macy’s Thanksgiving Day Parade which passes through Herald Square in New York City. Both began in 1924 and have been attracting hundreds of thousands of spectators each year.
