I've just started using the javascript .addMonth(1) function for
adding a month to the selected date.
It is working flawlessly so far.
I took a look for a subtractDay() function, but haven't found much.
Apparently you can use a php type date function in javascript
[code]
d = new Date(d.getYear(),d.getMonth(),d.getDate()+90)
[/code]
This page gives a bunch of info on manipulating dates in javascript.
As far as I've seen there isn't a simple jquery-esque way of
manipulating dates, but you can easily mix both jquery and javascript.
