Number of Days Before Christmas Counter in JavaScript

Here is a sample program that I wrote that will count the number of days before Christmas using JavaScript.

My email address are the following jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

My mobile number here in the Philippines is 09173084360.

My telephone number at home here in Bacolod City, Negros Occidental is (034) 4335675.
