> Do the methods which Joan Young and R616A passed on to the list take leap >years into account? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Joan, Thank you for responding. I should have clarified my question , though. What I was wondering was how one accounts for the leap years which occur BETWEEN the person's birth and death. Shouldn't there be a formula or rule of thumb to follow? If a person lives for 80 years, leap years would change a birth date significantly.
