Age Difference Calculator

Calculates the age difference in years, months and days from the birth dates of two persons. The age difference isn't an exact value, because the months have different lengths and also the length of a year varies, depending on whether it is a leap year or not. But as a practical and plausible value, which shouldn't specify a totally accurate time span, it is useful for intelligible statements. The length of a month here is calculated with the rounded value of 30 days. The names of the persons can be entered.
