Get Days Between two Dates in JavaScript

First a box was created on the web page. I first added a heading to the box. Then two input boxes were made for input. Input boxes were made. I have used the type date of the input box here.

This calculator will determine the interval between the two dates. Then who will turn that time into seconds. Then turn that time into day again. If you want, you can view this information as hours, minutes, seconds instead of days.

HTML Code:

I have added the necessary information of this Get Days Between two Dates calculator using the following html. First the basic structure was created.

Then the heading and input box. Then there is a submit button. At the end of all there is a display in which the calculated results can be seen.

<!--Basic structure of calculator-->
<div class="container">
 <!--Added a heading-->
   <div class="heading">Days Between Two Dates</div>
<!--Two input spaces-->
   <div class="inp-wrapper">
<!--Place to input 1st date-->
        <div class="date-wrapper">
          <label for="date-1">Start Date</label>
          <input type="date" id="date-1" />
        </div>
<!--Place to input 2nd date -->
        <div class="date-wrapper">
          <label for="date-2">End Date</label>
          <input type="date" id="date-2" />
        </div>
   </div>
<!-- Submit button -->
   <button id="submit">Submit</button>
<!-- Display -->

JavaScript:

Now is the time to activate this Get Number of Days Between Dates project using JavaScript. Of course, you need to have a basic idea about JavaScript.

   //The 'Submit Button' and 'Display' ids are set to constant
    let submit = document.getElementById("submit");
    let output = document.getElementById("output");

    submit.addEventListener("click", () => {
      //Create a Date object from input value
      let date1 = new Date(document.getElementById("date-1").value);
      let date2 = new Date(document.getElementById("date-2").value);

      //Check if the input dates are valid
      //If valid calculate the difference
      if (date1.getTime() && date2.getTime()) {
        //Calculate difference in time using getTime function
        //getTime calculates number of years since January 1,1970
        let timeDifference = date2.getTime() - date1.getTime();

        //Since this value is in milliseconds we need to convert it into days
        //We want the difference to be a non-negative number. Hence we use Math.abs()
        let dayDifference = Math.abs(timeDifference / (1000 * 3600 * 24));
//InnerHTML is a property of the HTML DOM.
        output.innerHTML = `Difference between the two dates is <span>${dayDifference}</span> days`;
      }

      //Else display that the input is valid
      else {
        output.innerHTML = "Please select a valid date";
      }
    });
