The first plan holiday due to the failure of third five year plan in independent India was taken in which of the following year?

1966

In 1966, the anticipated launch of the Fourth Plan coincided with a significant decline in the novelty of planning, accompanied by a severe economic crisis in India. Consequently, the government made a decision to initiate a 'plan holiday,' effectively postponing the implementation of the Fourth Plan. This plan holiday, spanning from 1966 to 1969, marked the first instance of such a break in planning since India's independence.
