    You will want to modify your WordPress theme so that the changes can be site-wide.

    1. Log in to your WordPress installation.
    2. Navigate to Appearance > Editor
    3. In the Templates section, go to header.php
    4. At the very beginning of header.php, insert your code :
    <?php
$date = time();

$contestStart = strtotime('2012-02-03 00:00:00');

if ($date < $contestStart) {
?>

<html>
    Insert your whole splash page here.
</html>

<?php
exit;
}
?>
//The normal template code should be below here.

    Don't forget to click the "Update File" button on WordPress when you're done; and like the others said, make sure that your specified time is synced with whatever timezone the server is in.

    // setup the start date (in a nice legible form) using any
// of the formats found on the following page:
// http://www.php.net/manual/en/datetime.formats.date.php
$contestStart = "February 1, 2012"; 

// check if current time is before the specified date
if (time() < strftime($contestStart)){
  // Display splash screen
}

// date has already passed
else {
  // Display page
}

    You don't have to wrap the content, you can have something like:

    <?php 

if ( time() < strtotime('2012-02-03 00:00:00') ) {
    echo "not yet!";
    exit;
}

//code here wont be executed

    Be careful of timezones! Your server might be in a different timezone than your content.

    I suppose technically your code's logic would work but yes, there are much better ways of doing this. However, for your purpose we will go simple.

    You should be comparing against a timestamp and not a string. Try this:

    <?php

// The current date
$date = time();

// Static contest start date
$contestStart = strtotime('2012-02-03 00:00:00');

// If current date is after contest start
if ($date > $contestStart) {
//contest content?
}

else {
// splash content?
}
?>

    You can put the splash and content components in separate .php files, and simply include() then within the conditionals.

    if ($date > $contestStart) {
    include("SECRETDIR/contest.php");
}

else {
    include("SECRETDIR/splash.php");
}

    You'll want to set up an .htaccess so that people cannot point their browsers towards secretdir and directly access contest.php
