Day Counter – Posted on Day 2 etc

Hi, guys.

I’m running a Big Brother website (Big Brother launches tomorrow).

On the site i have a heading on the single page with a custom string that gets the data we input through the dash board.

The custom string is –

<?php $day = get_post_meta($post->ID, "day", $single = true);
if ( $day ) { echo $day; } else { the_time('D j F'); } ?>

I was wondering if they was a script i could use to get the day that we posted the story automatically. – In the form of Day: 1, Day: 2 etc.

For example, on the sidebar we have a javascript that brings up the current “day number” in terms of days the house (Today being Day: -1)

If i put this javascript in place of the custom string, no matter if the article was posted 5 weeks ago, the date still shows the day for today.

I hope this makes sense and appreciate any help. – i have used the search function prior to posting.

For reference, the “day script” can be found here:
