Independence Day, observed annually on 14 August, is a national holiday in Pakistan. It commemorates the day when Pakistan achieved independence and was declared a sovereign state following the termination of the British Raj in August 1947. Pakistan came into existence as a result of the Pakistan Movement, which aimed for the creation of an independent Muslim state in the north-western regions of British India via partition. The movement was led by the All-India Muslim League under the leadership of Muhammad Ali Jinnah. The event was brought forth by the Indian Independence Act 1947 under which the British Raj gave independence to the Dominion of Pakistan which comprised West Pakistan and East Pakistan. That year the day of independence coincided with 27 Ramadan of the Islamic calendar, the eve of which, one of the five nights on which Laylat al-Qadr may occur, is regarded as sacred by Muslims.

The national flag of Pakistan, also known as the Flag of the Star and Crescent, is made up of a green field with a stylized tilted white crescent moon and five-pointed star at its centre, and a vertical white stripe at its hoist-end. Though the specific shade of green on the flag is mandated only as 'dark green', its official and most consistent representation is in Pakistan green, which is shaded distinctively darker. It was adopted by the Constituent Assembly of Pakistan on 11 August 1947, and it became the official flag of the Dominion of Pakistan on 14 August 1947, following independence from the British Empire. The flag was subsequently retained as that of the Islamic Republic of Pakistan in 1956 and remains in use as the national flag to this day.
