PHP Calendar

I have been searching the galaxy for a php calendar and have had some trouble. I know, I know, they are all over the place but I need just a BASIC calendar system that I can tweak. I am building a web app and have some requested functions to build into the calendar but I would really rather just use a pre-built simple calendar for the foundation of it all.

Anyone out there have any good references? Remember, I am looking for an anemic calendar to use as a base.

I am using the following on my website. It is very basic, but can do some pretty powerful things with some slight tweaking.

Code: Select all
