Here is a simple javascript countdown timer script to estimate the number of seconds and days left before new year. Very easy to implement. Just copy paste the source code to your HTML page. Feel free to modify it accordingly.

<script LANGUAGE="JavaScript">
 
function days_between(date1, date2) {
 
var ONE_DAY = 1000 * 60 * 60 * 24
 
var date1_ms = date1.getTime()
var date2_ms = date2.getTime()
 
var difference_ms = Math.abs(date1_ms-date2_ms)
 
return Math.round(difference_ms/ONE_DAY)
}
 
var current_date = new Date()
 
var new_years_date = new Date()
new_years_date.setYear(new_years_date.getFullYear() + 1)
new_years_date.setMonth(0)
new_years_date.setDate(1)
 
var days_left = days_between(current_date, new_years_date)
var time_left = days_between(current_date, new_years_date)*24*60*60
 
// Write the result to the page
if (days_left > 1) {
document.write("<b>There are " + time_left + " seconds left this year.That means "+
 
days_left +" days left </b>")
}
else {
document.write("<b>There is " + days_left + " seconds left this year.</b>")
}
 
</script>
