If you want to tell people how long your website live, you will need the following code:
*PS: I just do in my way. I like to put total days not years and days combination. You can add diffYears to your own count up text.
<script language=javascript>
function siteTime() {
window.setTimeout("siteTime()", 1000);
var seconds = 1000;
var minutes = seconds * 60;
var hours = minutes * 60;
var days = hours * 24;
var years = days * 365;
// Get current time
var today = new Date();
var todayYear = today.getFullYear();
var todayMonth = today.getMonth() + 1;
var todayDate = today.getDate();
var todayHour = today.getHours();
var todayMinute = today.getMinutes();
var todaySecond = today.getSeconds();
// Your blog go live date
var t1 = Date.UTC(2018, 11, 03, 00, 00, 00); // Start time in yyyy mm dd hh mm ss format
var t2 = Date.UTC(todayYear, todayMonth, todayDate, todayHour, todayMinute, todaySecond);
var diff = t2 - t1;
var diffYears = Math.floor(diff / years);
var diffDays = Math.floor((diff / days) - diffYears * 365);
var diffDaysShow = Math.floor(diff / days); //show days only
var diffHours = Math.floor((diff - (diffYears * 365 + diffDays) * days) / hours);
var diffMinutes = Math.floor((diff - (diffYears * 365 + diffDays) * days - diffHours * hours) / minutes);
var diffSeconds = Math.floor((diff - (diffYears * 365 + diffDays) * days - diffHours * hours - diffMinutes * minutes) / seconds);
// Customize your own text. You can use diffYears, diffDays etc.
document.getElementById("sitetime").innerHTML = "Palace has been open for " +diffDaysShow + " day(s) " + diffHours + " hour(s) " + diffMinutes + " minute(s) " + diffSeconds + " second(s).";
}
siteTime();
</script>After that, you need to put the following code to the place you want (normally is in footer).
<span id="sitetime"></span>
