Javascript Date Since Calculator

This is a simple piece of code to calculate the number of days since an event:

function daysSince(yr, mo, dy) {
var anniv_date = new Date(yr, mo-1, dy);
var today = new Date();
var diff = (today - anniv_date)/1000/60/60/24;

You call this within your HTML as daysSince(2001, 09, 30) where the parameters are the year, month, and day of the anniversary.

You can see an example of this at
