  var interval = Math.floor(seconds / 31536000);

  if (interval > 1) {
    return interval + " years";
  }
  interval = Math.floor(seconds / 2592000);
  if (interval > 1) {
    return interval + " months";
  }
  interval = Math.floor(seconds / 86400);
  if (interval > 1) {
    return interval + " days";
  }
  interval = Math.floor(seconds / 3600);
  if (interval > 1) {
    return interval + " hours";
  }
  interval = Math.floor(seconds / 60);
  if (interval > 1) {
    return interval + " minutes";
  }
  return Math.floor(seconds) + " seconds";
}
var aDay = 24*60*60*1000
console.log(timeSince(new Date(Date.now()-aDay)));
console.log(timeSince(new Date(Date.now()-aDay*2)));
