Calendar is displaying dates from the previous month???

[cturner]

My calendar displays dates from the previous month on the next month. I don't want those dates in the calendar. Can someone please tell me how I can fix this problem? Thanks in advance.

Here is the code that I am working with:
[code]
require "config.php";
// Gather variables from
// user input and break them
// down for usage in our script
if(!isset($_REQUEST['date'])){
  $date = mktime(0,0,0,date('m'), date('d'), date('Y'));
} else {
  $date = $_REQUEST['date'];
}

$day = date('d', $date);
$month = date('m', $date);
$year = date('Y', $date);

// Get the first day of the month
$month_start = mktime(0,0,0,$month, 1, $year);

// Get friendly month name
$month_name = date('M', $month_start);

// Figure out which day of the week
// the month starts on.
$month_start_day = date('D', $month_start);

switch($month_start_day){
    case "Sun": $offset = 0; break;
    case "Mon": $offset = 1; break;
    case "Tue": $offset = 2; break;
    case "Wed": $offset = 3; break;
    case "Thu": $offset = 4; break;
    case "Fri": $offset = 5; break;
    case "Sat": $offset = 6; break;
}

// determine how many days are in the last month.
if($month == 1){
  $num_days_last = cal_days_in_month(0, 12, ($year -1));
} else {
  $num_days_last = cal_days_in_month(0, ($month -1), $year);
}
// determine how many days are in the current month.
$num_days_current = cal_days_in_month(0, $month, $year);

// Build an array for the current days
// in the month
for($i = 1; $i <= $num_days_current; $i++){
    $num_days_array[] = $i;
}

// Build an array for the number of days
// in last month
for($i = 1; $i <= $num_days_last; $i++){
    $num_days_last_array[] = $i;
}

// If the $offset from the starting day of the
// week happens to be Sunday, $offset would be 0,
// so don't need an offset correction.

if($offset > 0){
    $offset_correction = array_slice($num_days_last_array, -$offset, $offset);
    $new_count = array_merge($offset_correction, $num_days_array);
    $offset_count = count($offset_correction);
}

// The else statement is to prevent building the $offset array.
else {
    $offset_count = 0;
    $new_count = $num_days_array;
}

// count how many days we have with the two
// previous arrays merged together
$current_num = count($new_count);

// Since we will have 5 HTML table rows (TR)
// with 7 table data entries (TD)
// we need to fill in 35 TDs
// so, we will have to figure out
// how many days to appened to the end
// of the final array to make it 35 days.

if($current_num > 35){
  $num_weeks = 6;
  $outset = (42 - $current_num);
} elseif($current_num < 35){
  $num_weeks = 5;
  $outset = (35 - $current_num);
}
if($current_num == 35){
  $num_weeks = 5;
  $outset = 0;
}
// Outset Correction
for($i = 1; $i <= $outset; $i++){
  $new_count[] = $i;
}

// Now let's "chunk" the $all_days array
// into weeks. Each week has 7 days
// so we will array_chunk it into 7 days.
$weeks = array_chunk($new_count, 7);


// Build Previous and Next Links
$previous_link = "<a href=\"".$_SERVER['PHP_SELF']."?date=";
if($month == 1){
  $previous_link .= mktime(0,0,0,12,$day,($year -1));
} else {
  $previous_link .= mktime(0,0,0,($month -1),$day,$year);
}
$previous_link .= "\"><< </a>";

$next_link = "<a href=\"".$_SERVER['PHP_SELF']."?date=";
if($month == 12){
  $next_link .= mktime(0,0,0,1,$day,($year + 1));
} else {
  $next_link .= mktime(0,0,0,($month +1),$day,$year);
}
$next_link .= "\"> >></a>";

// Build the heading portion of the calendar table
echo "<table border=\"0\" cellpadding=\"1\" cellspacing=\"1\" width=\"250\" class=\"calendar\">\n".
    "<tr>\n".
    "<td colspan=\"7\">\n".
