Hi Stan,
I have just tested this MySQL calendar (from Werner of "Webbausteine.de") the other day and this is really simple to use. Unfortunately this is all in German but maybe you can handle the Google translation on my tutorial page. This is "Open Source" and may be used (for free) or changed as you like.

The German holidays can be unchecked - so they will not be displayed anymore or you may change them. You can change all spelling to English in file "kalender.php" too. All scripts have very good comments to what is done (but also in German).
You just need your MySQL database and the script "installation.php" is going to set all tables automatically (you must call this file one time to install your database) after you have done all changes on file "verbindung.php" and after you have copied all files to your server. You also must have PHP 5.2 (or higher) on the server.
Set your connection data in file "verbindung.php" and you also set your personal passwords for the editor. In this file you may also set additional passwords for other users (as many as you like).
Then you just link to the CSS and JavaScript files at the "Beginning of the <Body> tag".
To display the calendar at your NOF page you just draw a text field to the width your calender shall be displayed and copy this DIV-ID into the "html code editor" of that text field.
Code:
<div id="kalender"></div>
Copy all files of that application to the same folder to your server, where your page with the calendar will be published to. You may call file "demo.htm" to test your calendar.
After installation you should delete file "installation.php" at your server.
These are all files you need:
verbindung.php - set connection to database and carries all your personal settings
installation.php - installs tables of database (call this just one time to install your tables)
kalender.php - calendar script
demo.htm - calendar demo file (just for testing)
kalenderscript.js - JavaScript file
kalenderstyle.css - CSS file
kalender_editor.php - call this file to edit your calendar
