If you're only gonna be having the event twice, you can do what I did on one of my sites: you can use the start date and time as the first event and the end date/time as the second event, it's technically just one event, but then in the CGCalendar templates, you simple "fake it" something like:
Code: Select all
<p>Date 1:<br />
{$event.event_date_start} <br />
Date 2: <br />
{$event.event_date_end}
</p>
