ltwCalendar is an event calendar programmed in PHP and currently uses mySQL as a database backend. With ltwCalendar, you can add single events or recurring events. Everything is in a very customizable layout and should be very easy to integrate with your site. Do keep in my though that my initial intent was to never release this code into the wild. I was just making this for a personal project. After I got done with it however I decided I would give it to the world. So, please don't think I should be your personal support tech for it. I am willing to help where I can, but this is not my full time job :).
