splitting list results into two columns

I have seen a few different examples but didn't get anything to work right for me. I have a calendar of events looping through by month and then record, but I am wondering if I can look at the months inputted and split them into two columns. They might not have twelve months filled in. This is an example:http://www.jdgordonadvertising.com/cfs_volunteer/calendar/index.php.

Here is my code so far:
// load records
list($calendarRecords, $calendarMetaData) = getRecords(array(
'tableName' => 'calendar',
'orderBy' => 'date',
));

-----------------------------
<h1>Calendar Of Events</h1>
<?php
$half=intval($calendarMetaData['totalRecords']/2);
$count=0;
?>
<table width="300" border="0" cellspacing="0" cellpadding="3">
<tr><td>
<?php $heading = ""; ?>
<?php foreach ($calendarRecords as $event): ?>
<?php if($heading!=date("F, Y",strtotime($event['date']))): ?>
<?php $heading=date("F, Y",strtotime($event['date'])); ?>
<span class="highlightCaps"><?php echo $heading; ?><br /></span>
<?php endif ?>
<?php echo date("l, F jS",strtotime($event['date'])); ?><br />
<?php echo $event['location'] ?> | <?php echo $event['time'] ?><br /> <?php echo $event['title']; ?><br /><br />
<?php $count++; ?>
<?php endforeach ?></td>
</tr>
</table>

The code above has an attempt to look at the # of records and split it into two columns which I found in a post but that didn't work. I would like to be able to do it by how many months and then split.

Any help is appreciated. thanks.
