Hi Elicia,
I'm not certain why you'd want to shutter the page itself until a certain date, but it's possible with Javascript. You can add something like this to the <head> of your page to redirect if certain time hasn't been reached:
<script>
(function(){
var now = new Date().getTime();
var open = Date.parse('2014-10-16');//change your date here
if (now < open) {
window.location.href = '//www.example.com';//replace example.com with your desired redirect
}
})();
</script>
I'd generally go with Cheryl's suggest though.
