Organise your week with agenda-calendar.php. All you have to do is initialize the variables at the beginning of the script, and you're set. This relatively elaborate script was assembled with the aid of smaller scripts like php-calendar.php login.php, javascript-cookies.js, and params.php.
Agenda Calendar was written to provide a unique look for each month of the year. To change this, you must edit the arrays declared at the end of the initial php block. You can try out a working example of agenda-calendar. User name: agenda, password: calendar.
