  1. The ical program (not the Apple one) developed in 1993 using Tcl/tk and still maintained, should be listed. A simple intuitive interface with a month display on the left and appointments on the right. Source is available at

  2. It would be *MUCH* more impressive if all these articles about Linux calendar applications, *ESPECIALLY* when they’ve been written in the past year, would REFRAIN from listing applications that are dead, abandoned, or otherwise no longer exist.

    I would actually like to use Lightening, but apparently they can’t comprehend that 99.99% of the time, I do *NOT* want to edit an existing calendar entry (especially for all those meetings where I didn’t set up the calendar invite), but I only want to *LOOK* at the event details. And in general the Google Calendar plugin is severely broken as well. Seems like there is no longer a USABLE desktop calendar for Linux. I do NOT want to have to use an Android app (makes it difficult to bring up a meeting link on the computer when the calendar is on a miniscule phone screen), and I do NOT want to use a browser for something not meant for a browser.
