A brief desciption of how to use the article or code. The class names, the methods and properties, any tricks or tips.

Blocks of code should be set as style "Formatted" like this:

//
// Any source code blocks look like this
//
        t1="10/10/2006" ;

        t2="15/10/2006";

 
   //Total time for one day
        var one_day=1000*60*60*24; 
//Here we need to split the inputed dates to convert them into standard format
for furter execution
        var x=t1.split("/");     
        var y=t2.split("/");
  //date format(Fullyear,month,date) 

        var date1=new Date(x[2],(x[1]-1),x[0]);
  
        var date2=new Date(y[2],(y[1]-1),y[0])
        var month1=x[1]-1;
        var month2=y[1]-1;
        
        //Calculate difference between the two dates, and convert to days
               
        _Diff=Math.ceil((date2.getTime()-date1.getTime())/(one_day)); 
//_Diff gives the diffrence between the two dates.

Remember to set the Language of your code snippet using the Language dropdown.
