This is a tool that is primarily intended to calculate a person's age, but is can be used to determine the number of years between any two dates.
If you enter the start date and the end date is not empty, the program will compute the number of years between the two dates. If the end date is empty, the program will compute the end date from the start date and adding the age.
If you enter the end date and the start date is not empty, the program will compute the number of years between the two dates. If the start date is empty, the program will compute the start date from the start date and subtracting the age.
If you enter the age and the start date is not empty, the program will compute end date; otherwise, if the end date is not empty, it will compute the start date. If both the start date and end date are empty, it won't do anything.
