December 1952 (Nham Thin [Year of the Dragon]): Since June, the CEFEO helicopter fleet has been expanded with eleven Westland-Sikorsky WS-51 "Dragonflies."

December 28, 1956 (Year of the Monkey [Binh Than]): An agreement is reached that brings the Pathet Lao's Patriotic Front (N?o lao Haksat or NLHS), which had boycotted the December 25 elections, into the new government.

December 28, 1964 (Year of the Dragon [Giap Thin]) (US Advisory): While representatives of General Khanh and the US meet to work out a solution to the governmental crisis in South Vietnam, the VC 9 Division seizes the Catholic village of Binh Gia east of Saigon and holds it for four days, ambushing and destroying a South Vietnamese Ranger battalion and a South Vietnamese Marine battalion, killing a total of 177 South Vietnamese soldiers and six of the Americans who accompany them. The Viet Cong leader in the battle, Duong Van Nhut, is the younger brother of the ARVN general and former head of state Duong Van Minh (Big Minh).

December 1966 (Year of the Horse [Binh Ngo]) (US Counteroffensive Phase II): As Operation Market Time limits smuggling operations along South Vietnamese waterways, the North Vietnamese, with the tacit agreement of Prince Norodom Sihanouk, start to use the port of Sihanoukville for transshipment of munitions destined for the Mekong Delta.
