I have a web-page that has the info, 'This page was last updated on (suppose) 04/08/2005.'

What I would like, is to have this date change every 7 days beginning from 04/08/2005.

I have to update this page every seven day, and I would like the date to change dynamically without me having to change it whenever I make some changes to the page or even if I don't make any.

Any help would be grately appreciated. Thanks.

hurray ji,
In what format are you passing your date ? Are you passing date in 04/11/2005 format for checking before updating ?

Any format. For now let's go with what you've mentioned.

//try this one, your comments are welcome.
function FormatDate(strDate) // strDate should be in the format of 04/11/2005 or 4/11/2005 is also ok.
{
var strEffectiveDate = 20050408; // this is your effective date 04/08/2005
var temp;
temp = "";
var i = 0;

var month ="";
var day = "";
var year = "";
var l1=0;
var stop1 = false;
var stop2 = false;;
var x = 0;

var date= "";

while(i < str.length)
{
if(stop1 == false)
{
if(strDate.charAt(i) != "/")
{
month = month + strDate.charAt(i);
l1 = l1 + 1;
}
}

if(strDate.charAt(i) == "/")
{
stop1 = true;
}

if(i>l1)
{
if(stop2 == false)
{
if(strDate.charAt(i) != "/")
{
day = day + strDate.charAt(i);
x = i;
}
}
if(strDate.charAt(i) == "/")
{
stop2 = true;
}
}

i = i +1;
}

i = 0;
while(i < strDate.length)
{
year = year + strDate.charAt(x+2+i);
i=i+1
}

if(month.length == 1)
{
month = "0"+month;
}

if(day.length == 1)
{
day = "0"+day;
}

date = year+month+day;

return date; //Now the strDate (04/11/2005) is in the format of 20050411

}

//Now update your page, First check your effective date

var diffDays;
if(FormatDate(yourCurrentDate) > strEffectiveDate )
{
diffDays = FormatDate(yourCurrentDate) - strEffectiveDate;

if(parseInt(diffDays) % 7 == 0)
{

//Referesh your page - beause it is in every 7 days increment.

}
}
