Add year to count up

Question

I am having trouble adding in a year to my count up code.

I have tried this:

days=Math.floor(difference/(60*60*1000*24)*1);
days=Math.floor(difference/(60*60*1000*24)*1/365);
hours=Math.floor((difference%(60*60*1000*24))/(60*60*1000)*1/365);
mins=Math.floor(((difference%(60*60*1000*24))%(60*60*1000))/(60*1000)*1/365);
secs=Math.floor((((difference%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1/365);

document.getElementById('countup').setAttribute("uptime",years+':'days+':'+hours+':'+mins+':'+secs)
document.getElementById('years').firstChild.nodeValue = years;
document.getElementById('days').firstChild.nodeValue = days;
document.getElementById('hours').firstChild.nodeValue = hours;
document.getElementById('minutes').firstChild.nodeValue = mins;
document.getElementById('seconds').firstChild.nodeValue = secs;

But it still didn't work. Also how would I allow for a leap year?

Can someone point me in the right direction. Is there an easier method for creating the same effect with jQuery?

I would recommend using a library like Moment.js rather than trying to reinvent the wheel. Otherwise, the calculation you'd need will be way more complicated than what you have so far. — evolutionxbox

jQuery is a DOM manipulation library so it's of absolutely no help for manipulating dates. — JJJ

That's cool @Frogmouth, although I think what OP is asking for is about accurately calculating the time between two dates (Years, Months, Days, Hours, and Seconds) whilst accounting for leap years/seconds. — evolutionxbox

I think you're going to have a rough time trying to create this in plain JS and jQuery isn't really an appropriate option as it's primarily a DOM manipulation library.

Instead, I recommend using Moment.js.

It's a library dedicated to this sort of thing and handles things which you probably weren't even thinking about (like Timezones).

Just browse through the code and see what I mean.
