This is Sanjay Ghemawat's Ical program designed for X-Windows systems. It stores calendars in its own proprietary ~/.calendar files.
It is NOT Apple’s iCal or the IETF iCalendar standard RFC2445, RFC5545 or successors.
Ical is a calendar application. Some of the important features are:
This site hosts a copy of Sanjay Ghemawat's Ical program created when he was at DEC, Palo Alto back in 1993.
It was originally hosted at DEC, Palo Alto and then also at MIT, but these sites are long defunct.
For a long time, the FreeBSD port pulled this software from an FTP mirror at ftp.sunet.se but, in around October 2019, that FTP site also stopped working.
Gabbar Singh has a useful Ical blog.
In around 2004-5, RedHat released a v2.3 update with patches to make it run on their system.
In around 2006, Richard W. M. Jones ran the Ical Maintenance Project at Annexia, releasing v2.3.1 and v2.3.2, but this is now also defunct. A copy can be found in the Intenet Wayback Machine. He also did a v2.3.3 version, but we have not been able to obtain a copy of this tar file.
Another hosting site is John Heidemann's site at ISI. This has the v2.3.1 update.
Since 2008, Sergei Golubchik has been maintaining a Launchpad project to add a small number of new features to Ical.
This site at Opal was created on 2019/12/20 in order to ensure that there are sufficient source sites remaining of this software and to collect all the various versions in a single site.
A FreeBSD port is available in the ports collection.
