i trying script display 3 dates in future, estimating arrival time if customer orders today. in advertising , on homepage want show 4, 10 , 12 business days in future, formatted "monday, january 12th", allow customers know approximately when might labels.

i able 3 dates in future, not accounting weekends or of dates in 'holiday date array,'

i need count 4, 10, , 12 business days future., code shown below counting days without skipping weekends or holidays.

my current js / jquery code:

var natdays = [ [1, 1, 'new year'],  [1, 20, 'martin luther king'],  [2, 17, 'washingtons birthday'],        [5, 26, 'memorial day'], [7, 4, 'independence day'],  [9, 12, 'labour day'], [10, 14, 'columbus day'], [11, 11, 'veterans day'], [11, 28, 'thanks giving day'],  [12, 25, 'christmas']    ];  // datemin minimum delivery date var datemin = new date(); datemin.setdate(datemin.getdate() + (datemin.gethours() >= 14 ? 1 : 0));  function addbusinessdays(curdate, weekdaystoadd) {   var date = new date(curdate.gettime());   while (weekdaystoadd > 0) {     date.setdate(date.getdate() + 1);     //check if current day business day     if (noweekendsorholidays(date)) {       weekdaystoadd--;     }   }   return date; }  function noweekendsorholidays(date) {   var noweekend = jquery.datepicker.noweekends(date);   return (noweekend[0] ? nationaldays(date) : noweekend); }  function nationaldays(date) {   (i = 0; < natdays.length; i++) {     if (date.getmonth() == natdays[i][0] - 1 && date.getdate() == natdays[i][1]) {       return [false, natdays[i][2] + '_day'];     }   }   return [true, '']; } function setdeliverydate(date) {   jquery('#normal-date').text(jquery.datepicker.formatdate('dd, mm dd', date)); } function setrushdeliverydate(date) {   jquery('#rush-date').text(jquery.datepicker.formatdate('dd, mm dd', date)); }function setsuperdeliverydate(date) {   jquery('#superrush-date').text(jquery.datepicker.formatdate('dd, mm dd', date)); } setdeliverydate(addbusinessdays(datemin, 12)); setrushdeliverydate(addbusinessdays(datemin, 10)); setsuperdeliverydate(addbusinessdays(datemin, 4)); ;
