How to pass input value of type 'date' to a function which Calculates and updates age every second

Question

I'm trying to create a live age counter which calculates & updates the age every second using setInterval(). It works with the predefined input but isn't working with the manual user input submitted through a date object. How to pass the input of type 'date' to the calculateAge() function I'm using.

//js file 
    function ageCalculator() {
        
        function startCal() {
            setInterval( function() {
                calculateAge();

            }, 1000);
        }
        function calculateAge() {
        

            var nowDate = new Date();
            // Example date of birth.
            var dob = document.getElementById("age-value");
            var dobDate = new Date(dob);
    
           
            
            var str = (years +":"+months+":"+weeks+":"+days+":"+hours+":"+minutes+":"+seconds);
            document.getElementById("age").innerHTML = str;
           
        }
    
       return {
           startCal : startCal
       }
    }

var ageCalculatorInstance = ageCalculator();
//ageCalculatorInstance.startCal();

Answer 1

This should give you the date entered by the user:

const input = document.getElementById("age-value").value;
const dateEntered = new Date(input);

Answer 2

Use document.getElementById("age-value"). value

and call the function as onclick="ageCalculatorInstance.startCal()"
