I am trying to get my head around the moment.js library as it seems more stable than the jquery one and the jquery date one is output console errors.

http://momentjs.com/docs/#/manipulating/

What i am trying to do is do a countdown to work out the time left from now.

example i have

var countDownTill = '2012-11-19 00:00:00 +0000';
document.write(moment(countDownTill).diff(moment(), 'months') + " months<br>");
document.write(moment(countDownTill).diff(moment(), 'weeks') + " weeks<br>");
document.write(moment(countDownTill).diff(moment(), 'days') + " days<br>");

which will output

0 months
1 weeks
4 days

but its not working out overall its doing it individuals for each value (days,weeks,months)

so if i up the date by say 12 months like below.

var countDownTill = '2013-11-19 00:00:00 +0000';
 document.write(moment(countDownTill).diff(moment(), 'months') + " months<br>");   
 document.write(moment(countDownTill).diff(moment(), 'weeks') + " weeks<br>");
 document.write(moment(countDownTill).diff(moment(), 'days') + " days<br>");

it outputs.

12 months
53 weeks
369 days

where as i am trying to get it to output

12 months
2 weeks
5 days
