No Google. It is not Christopher Reeves’ 69th birthday because he stopped having birthdays when he was 52. You know. Because, he died when he was 52.
Birthdays are celebrated by the living for the living. If you have a 16th birthday it is because you’ve lived that long. If you died when you were 5, you can’t possibly have a 16th birthday.
It is pretty simple really. I don’t know why we keep mis-using and mis-representing birthdays on Google.
It is ok to say “It *would have been* Christopher Reeve’s 69th birthday today.
On October 10, 2021, we can celebrate his death day.
