Special sessions of Parliament were historically called for crises and commemorations. In 2008, when the UPA government lost the support of the Left, in 1991 and 1977 to impose President's Rule in various states, and in 1962 during the war with China, special sessions were called in the wake of crises. Commemorative sessions have been called for anniversaries of the Quit India Movement, Ambedkar's birth anniversary, and the inauguration of the new Parliament, most recently in 2023.
