Just created a fresh project on google codes, a calendar class that is ultra flexible, super easy to use, and very fast :)

bbqq-calendar

A light weight calendar that can be used as a base for customized calendars, provides both HTML rich calendar and a plain text calendar that macheads can use for geektool.
It also supports customizable templates for various elements, such as wrapping tags, links, etc.
Date format can also be modified as well.
