// work out how far through the day we are as a percentage - e.g. 6pm = 75%
var hourpercent = hour / 24 * 100;
var minutepercent = minute / 30 / 24 * 100;
var percentofday = Math.round(hourpercent + minutepercent);

// calculate which pixel row to start graphic from based on how far through the day we are
var offset = backgroundheight / 100 * percentofday;

// graphic starts at approx 6am, so adjust offset by 1/4
var offset = offset - (backgroundheight / 1);

function scrollbackground() {
// decrease the offset by 1, or if its less than 1 increase it by the background height minus 1
offset = (offset < 1) ? offset + (backgroundheight - 1) : offset - 1;
// apply the background position
$('body').css("background-position", "50% " + offset + "px");

Luckily, there are many methods in safely removing unwanted
hair. Before you go for them, try products
at Keranique for hair care. A well groomed woman will look to her
hair and makeup first and a poll of 3,000 females across the UK revealed that about 44% feel attractive if they are having a good hair day, this compares to 16% who felt pleased with their
appearance if good teeth gave them that winning smile.
