Jinnah's birthday, officially Quaid-e-Azam Day and sometimes known as Quaid Day, is a public holiday in Pakistan observed annually on 25 December to celebrate the birthday of the founder of Pakistan, Muhammad Ali Jinnah, known as Quaid-i-Azam ("Great Leader").

The event is primarily observed by the government and the citizens of the country where the national flag is hoisted at major architectural structures such as private and public buildings, particularly at the top of Quaid-e-Azam House in Karachi.

[3] In 1942, numerous events commemorated Jinnah on his birthday, 25 December: the All-India Muslim League organised a fund for the poor and Liaquat Ali Khan held a reception for the leader.

[4] From then on, numerous events were held yearly on 25 December to honour Jinnah during his lifetime; this included receptions, parades, commemorations, speeches and recognition from other world leaders.

[6][7][8] The unified ritualistic event, usually attended by prominent leaders, military commanders and citizens, is organised at Mazar-e-Quaid, and while it is aimed at to highlight the life of Jinnah, all public and private sectors,[9] including schools, colleges and universities[10] remain closed to organise multiple events such as debates, seminars and exhibitions at respective locations without being involved in office management.
