The phrase "Patriot Day countdown" functions as a compound noun phrase.

Thus, the entire phrase denotes the period leading up to September 11th, the day officially designated as Patriot Day in the United States.
Patriot Day is an annual observance in the United States that commemorates the victims of the September 11, 2001, terrorist attacks. Established by a joint resolution of Congress in December 2001 (Public Law 107-89), it calls for the display of the American flag at half-staff and a moment of silence observed at 8:46 AM Eastern Daylight Time, marking the time the first plane struck the World Trade Center. A "countdown" to this date therefore serves to highlight the approaching anniversary, prompting individuals, communities, and national institutions to prepare for solemn remembrance, honor first responders, and reflect upon the enduring impact of the events and the nation's resilience. It transforms a simple date into a focal point for collective memory and contemplation.
Practically, a "Patriot Day countdown" can be featured on websites, news platforms, or community portals to heighten public awareness, encourage participation in memorial events, or facilitate personal reflection on the significance of the day. Conceptually, it represents a period of anticipation for an event of national mourning and remembrance, emphasizing the importance of not forgetting the tragic losses and the lessons learned from that pivotal day in American history.
