This took me some time:

 

When you use client-side code (the Document.Cookie property) to write cookies, and then use the same method to retrieve the cookies, you may receive an empty string or the following error message:

 
ERROR_INSUFFICIENT_BUFFER
 
From here.
 
So, I guess, better don't use JavaScript setcookie, rather use server - side setting cookies.

First, code for increasing day. If we have date in string, then code would look something like this:

strYear = strDate.substring(0,4);
strMonth = strDate.substring(5,7);
strDay = strDate.substring(8,10);
d = new Date(strYear, strMonth - 1, strDay);
d.setDate(d.getDate() + 1);

Then, to format date time, to something like yyyy-mm-dd, I was using this code:

strYear = d.getFullYear();
if (d.getMonth() < 10)  {  
	intMonth = d.getMonth() + 1;
	strMonth = '0' + intMonth;
} else  {
  strMonth = d.getMonth() + 1;
}
if (d.getDate() < 10)  {
  strDay = '0' + d.getDate();
} else {  
	strDay = d.getDate();   
}

Finnaly, date would be created something like:

strDate = strYear + '-' + strMonth + '-' + strDay;

getMonth - with this function we are geting number of a month, but from 0, 0 - this is January?
getDate - with this function we are geting number of a day in a month.
