Reunification Day (Ngày Thống nhất), Victory Day (Ngày Chiến thắng) or Liberation Day (Ngày Giải phóng or Ngày Giải phóng miền Nam) is a public holiday in Vietnam that marks the event when Viet Cong and North Vietnamese troops captured Saigon (now Ho Chi Minh City) on April 30, 1975. This signalled the end of the Vietnam War, known in Vietnamese as Chiến tranh Việt Nam (Vietnam War) or Kháng chiến chống Mỹ ("Resistance War Against America"). It was the start of the transition period toward reunification, which occurred July 2, 1976, when the Provisional Revolutionary Government of the Republic of South Vietnam and North Vietnam merged to form the modern-day Vietnam or the Socialist Republic of Vietnam.
