<!-- TWO STEPS TO INSTALL DAYS REMAINING IN YEAR:

1.  Copy the coding into the HEAD of your HTML document
  2.  Add the last code into the BODY of your HTML document  -->

<HEAD>

<!-- Begin
function days_between(date1, date2) {
  // The number of milliseconds in one day
  var ONE_DAY = 1000 * 60 * 60 * 24

// Convert both dates to milliseconds
  var date1_ms = date1.getTime()
  var date2_ms = date2.getTime()

// Calculate the difference in milliseconds
  var difference_ms = Math.abs(date1_ms - date2_ms)

// Convert back to days and return
  return Math.round(difference_ms/ONE_DAY)
}
//  End -->
</script>

</HEAD>

<BODY>

<!-- Begin
// Store the current date and time
var current_date = new Date()

// Store the date of the next New Year's Day
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)

// Call the days_between function
var days_left = days_between(current_date, new_years_date)

// Write the result to the page
if (days_left > 1) {
  document.write("<b>There are " + days_left + " days left this year.</b>")
}
else {
  document.write("<b>There is " + days_left + " day left this year.</b>")
}
//  End -->
</script>
