Thank you very much.

You're looking for a plugin that does relative or friendly dates. I would recommend the timeago jQuery plugin for this.

jquery animate can do many things.please go through the below api

http://api.jquery.com/animate/

you can even use interval

setInterval(function() //

Take the time in seconds, and divide it by the number of seconds in a year, and that's how many years. Subtract that then divide it by the number of seconds in a month, and that's how many months. Subtract that then divide it by the number of seconds in a week... etc.
