Three grandfathers in my family share a death date in different years

My paternal grandfather died on November 21, 2005. My maternal grandfather died one year later on November 21, 2006. As the only child of my father, I am the only one to share these two grandfathers. This year, my first cousins (my mother's sister's daughters) now have this in common with me. Their father's father died on November 21, 2019. Also, my maternal grandfather was born on 12-12-21 and his great grandson (son of one of my cousins mentioned above who just lost their other grandfather) was born on 12-21-12.
