Pakistan Day ( Republic Day) youm e pakistan

Pakistan Day (Urdu:  Youm-e-Pakistan) or Republic Day is a national holiday in Pakistan to commemorate the Lahore Resolution of 1940 and the adoption of the first constitution of Pakistan during the transition of the Dominion of Pakistan to the Islamic Republic of Pakistan on 23 March 1956 making Pakistan world's first Islamic republic.

Pakistan had obtained its independence from the British Raj the 14th of August 1947. 23 March was originally supposed to commemorate the adoption of the first constitution of Pakistan and thus the declaration of Pakistan as a republic. However, Field Marshal Ayub Khan abrogated the constitution and declared martial law. Khan's regime, in order to justify celebrating the national day, changed it to commemorate the 1940 landmark, during which All-India Muslim League passed the Lahore Resolution which later cemented the formation of a new nation in the sub-continent as Pakistan, even though it did not actually mention Pakistan at all. The Muslim League annual conference was held from 22–24 March 1940 and the Lahore Resolution was passed on 23 March.

Celebrations
The celebrations regarding the holiday include a full military and civilian parade in the capital, Islamabad. These are presided by the President of Pakistan and are held early in the morning. After the parade, the President confers national awards and medals on the awardees at the Presidency. Wreaths are also laid at the mausoleums of Muhammad Iqbal and Muhammad Ali Jinnah.
