The Vietnamese new year is known as Tet .
Although a giỗ is nearly always a private ceremony only attended by a family and occasionally also close friends , in 2007 , a new public holiday called Giỗ tổ Hùng Vương ( giỗ of the Hùng King ancestors ) has been instituted in Vietnam to commemorate the Hung Kings , the legendary founders of the first Vietnamese kingdom in Vietnam 's remote past , although it had been unofficially commemorated for thousands of years .
