Hi Experts,

What is the function to add a number of days to a date?

I found this but I need it to add days:

<script>

var actDate = new Date() // now()

alert(addMonths(actDate, 3));


function addMonths(theDate, amtMonths){
  var xDate = new Date(theDate);
  return new Date(xDate.setMonth(xDate.getMonth()+(amtMonths*1)));
}

</script>

THANKS

var dtmDate = new Date( )

Sorry one last quick question, how can I get the date to display as "dd/mm/yyyy" and also as "Sunday,March 3,2007"?

Thanks

formatDate(yourDateVariable, FormatString)  

where in your case, the FormatString would be "EE, MMM d,yyyy"

I have this in the format I want but I don't know how to add days

   var d = new Date()

var weekday=new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday")
var monthname=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec")

colDate = weekday[d.getDay()] + " " + monthname[d.getMonth()] + " " + d.getDate() + ", " + d.getFullYear()



   alert(colDate)

    }

Oh that, was for displaying as "Sunday, March3,2007"

For "dd/mm/yyyy" use te format string "dd/MM/yyyy"

All I want is to modify the following script to add x number of days to the current date. How can I do this?



  function  InsertCollectDateToList(zonename)
   {
   
   var myarra1=array23;
   var zonename;

   var colDate;

   var weekday=new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday")
   var monthname=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec")

   colDate = weekday[d.getDay()] + " " + monthname[d.getMonth()] + " " + d.getDate() + ", " + d.getFullYear()

   alert(colDate)

   }

I now have this but it doesn't work

function AddDays(strDate,intDays){
      strDate = Date.parse(strDate);
      strDate = parseInt(strDate, 10);
      strDate = strDate + intDays*(24*60*60*1000);
      strDate = new Date(strDate);
}


  function  InsertCollectDateToList(zonename)
   {
   
   var myarra1=array23;
   var zonename;

   var d = new Date()

   var strDate ="<%=newformatDateTime(Date(),"M2/D2/Y2",0)%>"

   var colDate;



   var weekday=new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday")
   var monthname=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec")



   colDate = weekday[d.getDay()] + " " + monthname[d.getMonth()] + " " + d.getDate() + ", " + d.getFullYear()

   alert(AddDays(strDate,1))

   }
