Vietnam Veterans Day commemorates the sacrifices of Vietnam veterans and their families and is part of a national effort to recognize the men and women who were denied a proper welcome upon returning home more than 40 years ago.

The Vietnam War Veterans Recognition Act, signed into law in 2017, designates March 29 of each year as National Vietnam War Veterans Day.

Most states celebrate “Welcome Home Vietnam Veterans Day” on March 29 or 30 of each year. Though there is some debate, March 29 is generally viewed as a more appropriate date. On that day in 1973, the last combat troops were withdrawn from Vietnam and the last prisoners of war held in North Vietnam arrived on American soil. It is also the date President Nixon chose for the first Vietnam Veterans Day in 1974.

Note 47 states and Puerto Rico recognize Vietnam Veterans Day either annually or for a specific year.
