I need multiple stylized circular countdown clocks -- 2

I want a circular countdown that counts in days, minutes and hours for more website. I want it in javascript and style in css or if possible html5 with css. So the way it should work is it should be a countdown always counting down from either years, months, days, or minutes. Everytime it changes from 1 year to Days or from days to hours the color of the circle should change. I have more detail avaialble, and a more personal sample of an image I created myself once you are picked for this project. Please only apply if you're a javascript, css3, html5 expert. If possible I would like to avoid other programming languages. Jquery is fine as long as I dont have to add many scripts to my site. The size of the circle should be around 50x50 Pixels but that may change.
