How to subtract days from a plain Date?

Is there an easy way of taking a olain JavaScript Date (e.g. today) and going back X days?

So, for example, if I want to calculate the date 5 days before today.

Try something like this:

var d = new Date();
 d.setDate(d.getDate() - 5);

Note that this modifies the date object and returns the time value of the updated date.



var d = new Date();

document.write('Today is: ' + d.toLocaleString());

d.setDate(d.getDate() - 5);

document.write('
5 days ago was: ' + d.toLocaleString());
