Commemorates the 'Lahore Resolution' of 1940, also known as the 'Pakistan Resolution' that eventually led to the creation of Pakistan.
The day is being observed as a public holiday in all federal and provincial government offices, banks and private sectors.
On 23 March 1940, the Lahore resolution was passed which rejected the concept of a United India and proposed the creation of an independent state for Muslims, even though it did not actually mention Pakistan at all.
The resolution paved the way for the creation of Pakistan on 14 August 1947, when Pakistan became the world's first Islamic republic. 14 August is celebrated as a holiday - Independence Day.
The holiday is celebrated with early morning military and civilian parades in Islamabad with gun salutes in Islamabad and provincial capitals.
Later in the day, the President confers national awards and medals Presidency. Wreaths are also laid at the mausoleums of Muhammad Iqbal in Lahore and Muhammad Ali Jinnah in Karachi.
