There is no exact date. The first advisor's were sent to Viet Nam during the Kennedy administration. Some historians even say we sent some during the Eisenhower years. U.S. involvement in the war just slowing progressed year after year.

That is a difficult question to answer, and varies on who you ask. Some say the Vietnam conflict (there was never an official declaration of war) started in 1955 when the U.S. started to send military advisors to South Vietnam. The first American military advisors killed by enemy combatants occurred in 1959. Some point to late 1961 when President Kennedy sent the first helicopter group & U.S. service men to fly them in support of South Vietnamese troops. Many say the war officially started with the Gulf of Tonkin resolution in August 1964, which gave President Johnson basically free reign to escalate the war. And some people say the war really started in March 1965 when the first American combat troops (Marines) arrived in South Vietnam.
