You can get value from that 6 fields and arrange them shown below:

date_from=new Date('FROM_YEAR','FROM_MONTH','FROM_DAY');
date_from =  date_from.getTime();

date_to=new Date('TO_YEAR','TO_MONTH','TO_DAY');
date_to =  date_to.getTime();

if(date_from > date_to)
{
    alert("Please enter valid date");
    return false;
}
