Active Calendar is PHP Class, that generates calendars (month or year view) as a HTML Table (XHTML-Valid). Active Calendars source code is free.

can be static (without any links)
can optionally have navigation controls
can optionally have a date picker control
can optionally have linkable days (url or javascript)
can optionally have event days with event links and own layout
can optionally have event content with links and own layout

can be configured using CSS
do not require Javascript to be displayed or navigated (server side generation)
can be generated with just 2-3 lines of code
Active Calendar is based on the PHP native date functions (default) and supports optionally the ADOdb Date Library. Supported dates (on systems using a 32-bit signed integer Unix time_t):
Using PHP native date functions: 1902 - 2037 (UNIX) and 1971 - 2037 (Windows)
Using ADOdb Date Library: 100 - 3000 and later [ limited by the computation time of adodb_mktime() ] on both UNIX and Windows. To use the ADOdb Date Library just include it in your scripts. The Active Calendar class will use the library functions automatically.
Enhancements:
- An activeCalendarWeek subclass was added.
- The class can generate week calendars (one or multiple rows) according to the date or the week number of the year passed to the class using two public methods, showWeeks() and showWeeksByID().
- The structure of the download package was updated and an example was added for demonstrating how the Active Calendar can be used as a popup date selector in a form.

Calendar is a web-based calendar tool that produces pretty, readable calendars. NEW! Rewritten in Java for MySQL! Calendar project began out of frustration with other web-based calendar tools inability to display a readable calendar format. It was very much a project to "scratch an itch" -- to meet an immediate need that the author had. Since then, it has evolved considerably into a very useful tool that produces prettier calendars than those printed by most organizer software.
Main features:
- NEW! Subscriptions can be created to periodically fetch events from remote calendars, just like iCal and Sunbird can do.
- Events on the calendar appear exactly as typed in the admin tool -- the descriptions are not cut off in the display. This makes the calendar just as useful when its printed.
- The entire calendar is rendered in HTML -- no Flash or Java is used.
- Single-day, multi-day and occassional events are all supported. ("Occasional" events are those events that occur multiple times but dont necessarily follow a regular pattern.)
- Repeating events are supported and can repeat on a daily, weekly, monthly or yearly basis.
- Events may be categorized for easy administration.
- Nearly everything about the display is themable -- colors, fonts, border styles, first day of the week, weekday column widths, categories, etc.
- A calendar may be setup as a "private" calendar, so the user must be logged in to see it.
- NEW! A calendar may be setup as a "semi-private" calendar, so the user will only see the scheduled times but no event details.
- The admin tool is password protected and different users can be assigned different permission levels.
- Apple iCal and Mozilla Sunbird users can subscribe to the calendar with one click.
- A really bland, unimaginative name makes it easy to discuss this project without being overheard by foreign intelligence agents.
The first version of this software was written in ASP (VBScript) and ran on IIS 4.0 or higher with a database on SQL Server 7.0 or higher. The current version has been completely rewritten in Java to run on Tomcat 5.5 or higher with a database on MySQL 3.3 or higher. The feature set has grown immensely since then. The two versions have no code in common.
