A better answer would be to do it properly, except that as earlier
said I suggest that years and days is a better way to go.

Here is some code. It has not been very much tested. It is a bit
messy, because it needs to be general enough to deal with leap years
and with persons born on February 29 (two related but not identical
problems).


Dear Nick:
I am delighted with your kindness in going ahead with my question.
I will try your solution in a set of data I concocted to test a very rough code I made, before starting the trhread.
As soon I got the results I inform you.
Thank you very very much.
