Time is money, as goes an old saying, therefore you need to manage it very well. This then calls for proper planning of your daily schedule, future events, appointments, and several other daily activities.

Is there any calendar app with some remarkable components missing in the list above, then give us feedback through the comment section below.
What, no mention of Orage Calendar? It beats out all of the above. It is small, can sit on your desktop and has easy to use reminders and notifications. I wouldn’t be without it. Often, I will remove the default calendar that comes with an OS and replace it with Orage Calendar. One of the best.
@Friar,
Thanks for notifying about Orage Calendar application, we will include in the list..
My wife uses Orage Calender like a demon. We both use Xubuntu on our desktop and laptop computers, but I use Calcurse as my main calendar, because it just works better for me.
A calendar should not only be useful for planning and remembering future appointments but also to keep track of old appointments. For the diary function of the calendar, it should be possible to edit the text of expired appointments.
This is possible in Logenda. That program also has a function to search in appointments. Its scrollable calendar display gives an easy survey of a complete calendar year.
LoGenda is a program for PC Linux (Ubuntu).
@Nelly
Many thanks for the useful feedback and for sharing LoGenda. We’ll check it out.
I know this will go against what us Linux users would ever recommend but it’s such a good calendar I have to mention it. Microsoft Calendar. I use both it and Google Calendar.
Microsoft Calendar for work-related and Google for my personal, or non-work-related. WebCatalog was used to create desktop apps of each and both are fantastic.
It’s spelled “calendar” with an “A” in calendAr not calendEr.
just a quick search and replace and your article will be spotless !
Thanks!
@Julius
Many thanks for the heads up, we have updated the article with the correct spelling.
MineTime is a new, modern and multi-platform calendar app. Connects to many calendars providers. https://minetime.ai
(Disclaimer: I am one of the developers)
@Marco
Many thanks for sharing this with us, we’ll check it out and review it as well.
I would like to know which of these programs supports CalDAV (or connects with Google Calendar).
@Daniel
Lightning (Thunderbird Extension), Evolution, Korganizer and California all support CalDav and should support Google Calender.
Thank you so much!
“calcurse” is so fantastic!
How about something like Plan? Looks like a simple but functional calendar app with a terrific bird’s eye view of monthly appts/notes. I’m searching high and low for this kind of calendar view – where you see the entire month in full screen and events/journal entries/etc can be gleaned. It’s writen in X/Motif and pretty old though..
https://www.bitrot.de/plan.html
California also has the same, full-screen view but this thing has been in development for years now and it’s still considered “new”. By the time they’re done, it’ll be as feature-bloated as everything else.
@derrick
We shall definitely try it out and possibly review it here as well. Thanks for getting back.
I use Google the Calendar but with the Korganizer
That is a good option, we shell have to try it out and see how it works. Thanks for the feedback.
You forgot my favorite calendar application… calcurse! I’ve been using it for years now, and can’t live without it!
@Howard,
Actually we haven’t forgot, fact is we really don’t know about the calcurse tool, but thanks for suggesting, we will include to the list..
@Howard,
As per your suggestion, we’ve included your favorite calender application called ‘Calcurse’ to the list, hope you like it..
