if someone died on October 4, 1907 and they were 58 years old, 9 months and 8 days old, what was their birthda?
Lame question, I know, but I haven't done math like this in about 20 years.
Their gravestone basically says (in German) Died at age 58 years, 9 months, and 8 days. On October 4, 1907.
Thanks for your help, this kind of thing makes my brain hurt.
