The keyword phrase functions as a proper noun phrase. It acts as a specific name for a date of historical and national importance, directly linking the calendar day of September 11th with the individual known by the title Quaid-e-Azam. Grammatically, it is not a verb, adjective, or common noun; it is a fixed designator for a specific event.
This date marks the death anniversary of Muhammad Ali Jinnah, the founder of Pakistan, who is honorifically referred to as Quaid-e-Azam ("Great Leader"). He passed away on September 11, 1948, just over a year after the country's independence. The event is a pivotal moment in Pakistan's history, representing the loss of its primary founding father during the nation's formative period. The day is observed annually in Pakistan as a day of mourning and remembrance.
In practice, the observance of this day is a solemn public holiday. It involves official ceremonies, special media broadcasts reflecting on Jinnah's life and vision, and public tributes at his mausoleum in Karachi. The date serves as an occasion for national reflection on his principles of "Unity, Faith, and Discipline" and the legacy he established for the state of Pakistan.
