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

understandinguncertainty.org was produced by the Winton programme for the public understanding of risk based in the Statistical Laboratory in the University of Cambridge. The aim was to help improve the way that uncertainty and risk are discussed in society, and show how probability and statistics can be both useful and entertaining.

Many of the animations were produced using Flash and will no longer work.

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.
