"sunbird" is available for most OS's including Linux.
Down load it and it run right out of the box.

The only thing that is odd is that you need to use the "network" option and 
set up the file  as  "file:///"Path"/filename.   It can be installed on a 
server and everyone can have access.

Some times when I get working on a problem I forget to go home so I put a 
reminder on the Calendar.
Good thing I don't have a dog or I would never get fed.  :-)
  
A well done SW package.
