<script>

function setCookie(name, value) {
  var exp = new Date(); 
  exp.setTime(exp.getTime() + (expDays*24*60*60*1000));

// Main Logic
var visitName = getCookie("visitorName");
var lastVisit = getCookie("lastVisitTime");
var currentVisit = new Date().toLocaleString();

  setCookie("visitorName", visitName);
  setCookie("lastVisitTime", currentVisit);
  document.write("Hello " + visitName + "! This is your first visit.");
} else {
  // Returning visitor
  document.write("Welcome back, " + visitName + "!<br>");
  if (lastVisit) {
      document.write("Your last visit was on: " + lastVisit);
  }
  // Update the time for next visit

Frequently Asked Questions

The script includes an expiration parameter. By default, it is set to 365 days, but you can adjust the 'expDays' variable in the code.

No. If a user has disabled cookies in their browser settings, this script will not be able to save or retrieve the visit data.

Since this script stores personal data (potentially a name), you should ask for user consent via a cookie banner before running the script to be fully compliant.
