Competing Web-based Calendars

Most don't point out their competition. We think healthy competition is a good thing :-)

• Kronolith: A PHP-based calendar that is part of the Horde Application Framework
• Chronos: a mod_perl-based calendar
• MRBS: Meeting Room Booking System. A PHP-based schedule for conference rooms that was originally based on an older version of WebCalendar.
• Jax: PHP-based event calendar that can use MySQL or flat files.
• Plans: a Perl/CGI-based event calendar
• Prospector: Perl/DBI rather than PHP. Looks very much like Yahoo! Looks like development has stalled since June 2001.
• myPHPCalendar: A PHP-based calendar
• mod_perl Calendar: Perl-based calendar last updated in 1999
• phpScheduleIt: A PHP-based reservation system

There are also quite a few groupware suites that include calendar modules:

• eGroupware: PHP-based groupware project
• TUTOS: PHP-based groupware project
• BORG Calendar: A Java-based calendar and task tracker
• phpGroupWare: A PHP-based office suite. The calendar was based on an earlier version of WebCalendar.
