I would like to see a calculator that would allow me to enter a name and see how old a person was when an event happened. For example, how old was my grandfather when his wife passed away? How old was my ancestor when a particular date or event happened? Like when he moved from one place to another.
I've often wondered how old someone was when something else happened, such as a move, the birth of a child, a divorce, the death of a spouse. You automatically show the age of a person when they got married, I just want a way to figure a person's age when other things happen in that person's life.
