If between two dates

[miles_rich]

I am having problems with this can anyone help.
I need to flag up when some one selects between the two weeks before christmas and the two weeks after christmas.

so i came up with.

$explode_travel_date = explode("/", $travel_date);
$quote_date = $explode_travel_date[0]."-".$explode_travel_date[1];
if (($quote_date <= '09-01') && ($quote_date >= '11-12'))
{
$date_link = "Christmas week";
}

date("W") returns "ISO-8601 week number of year, weeks starting on Monday (added in PHP 4.1.0)"(from PHP manual)

<?
$date = '12/01/03';

$timestamp = strtotime ($date);
$timestamp_xmas = mktime (0,0,0,12,25,2003);

if (($timestamp > ($timestamp_xmas - 1209600)) && ($timestamp < ($timestamp_xmas + 1209600))) {echo $date . ' is within 2 weeks before or after Chritmas 2003.';}
else {echo $date . ' is NOT within 2 weeks before or after Chritmas 2003.';}
?>
