Question: Write a javascript to get difference between two dates.

Answer: now = new Date();
newYear = new Date(2004,0,1);

secs = Math.round((now-newYear)/1000);

days = Math.floor(secs / 86400);
secs = days*86400;
hours = Math.floor(secs / 3600);
secs = hours*3600;
minutes = Math.floor(secs / 60);
secs = minutes*60

document.write(days + " days, " +
hours + " hours, " +
minutes + " minutes, and " +
secs + " seconds.");
