National VFW Day is celebrated on September 29th each year. This day honors the Veterans of Foreign Wars (VFW) and its members for their service to the nation and their continued commitment to veterans and their communities, according to the Harbor Gateway North Neighborhood Council and Veterans of Foreign Wars. The VFW was founded on September 29, 1899, by a group of veterans returning from the Spanish-American War, according to Harbor Gateway North Neighborhood Council and Veteran.com. It has since grown into the largest organization of combat veterans in the United States, according to Harbor Gateway North Neighborhood Council and the IHG Army Hotels Blog.
