Hi there,
For an educational app I want to calculate someone's age based on date
of birth and todays date but I don't know how to start!
I made a field in which the user puts its 'date of birth' (dd/mm/yy)
and a button that needs to compare 'todays date' and the 'date of
birth'.
The output needs to be : age and months (and days?)
It's late and maybe I have missed the point, but why have all the
scripts in this thread been so complicated? William seems to want
answers like "20 years, 6 months and three days". If one knows the
year of a person's birth - which can easily be converted into a full
4-digit number, and one knows the current year (ditto), then by
subtraction one knows the number of years the person has been alive.
After that, all you need to know is whether the person's birthday has
already occurred this year or not, and the number of days (365 or
366) in this year. AFAIK, what we mean by "20 years, 6 months and 3
days" is actually "6 months and three days after his/her 20th
birthday": it is not necessary to count precisely the number of days
the person has been alive. What did I miss in thinking like this?
