Age calculation

Hey there,

I'm creating an XLSForm to be used on ODK application and I want the user
to enter their date of birth and then to have an equation to calculate the
age- is that possible?

Thanks,
Mai

Hi Mai,
I Have an idea and i want to share it with you.

  1. the field of the date of birth must be a required field, its
    appearence must be "year" . in this example, i ask for the year of birth
    not the full date of birth.
  2. a calculated field AGE: calculation=2014-${Datebirth}

If you want the full date, you have to extract to year in the full date
before making the subtraction.

  1. fisrt of all, create a required field "birthday" and make its
    appearance "year" to make sure to capture the year of the birth day, not
    the full date of birth and its constraint=.<=2014
  2. create a calculated field et make its calculation =2014-${birhtday}
  3. but if you choose to aks for the full date of birth, you have to
    extract the year in the full date before subtracting it to 2014.
