Example 1 : Get Random Date Between Range using Javascript

In this example, we use a JavaScript function to generate random dates between two dates. The function takes two parameters: startDate and endDate, which are Date objects. It returns a new Date object that is randomly chosen between the startDate and endDate (inclusive). The function uses the formula Math.random() * (endDate - startDate) + startDate to calculate the random date

Get Random Date Between Range Javascript

 <script>
  function getRandomDate(start, end) {
   var startDate = start.getTime();
   var endDate = end.getTime();
   var randomTimestamp = Math.random() * (endDate - startDate) + startDate;
   var randomDate = new Date(randomTimestamp);
   return randomDate;
  }
 </script>

<script>
 var startDate = new Date('2023-01-01');
 var endDate = new Date('2023-12-31');

 function getRandomDate(startDate, endDate) {
  var randomTime = startDate.getTime() + Math.random() * (endDate.getTime() - startDate.getTime());
  var randomDate = new Date(randomTime);
  var formattedDate = randomDate.toISOString().split('T')[0];
  return formattedDate;
 }

 function generateRandomDate() {
  var randomDate = getRandomDate(startDate, endDate);
  // Display the random date on the web page
  var resultContainer = document.getElementById("result");
  resultContainer.innerHTML = randomDate;
 }
</script>
