Calcurse – A CLI Based Calendar and Scheduling Tool Linux

When you decide to fully dive into the Linux system ecosystem, you will soon realize that time is never fully on your side. You will want an organized time map to manage your computing objectives but find yourself failing to check some boxes just because you have not yet discovered the importance of having a calendar and scheduling tool on your Linux system.

This article will walk us through the installation and basic usage of a CLI-based calendar and scheduling tool called Calcurse.

Why Need a Calendar and Scheduling Tool in Linux?

Events, meetings, and project assignment dates can be costly to a Linux user if you do not find a way of effectively managing them. The following reasons best describe why you would need a calendar and scheduling tool for your Linux operating system distribution.

Plan for Your Projects and Daily OS Routines

Spending an unmetered time on the Linux terminal might seem productive but if your daily objectives are not in line, you could be slowly losing your productivity level. Having a calendar and scheduling tool helps break down your daily work time into small manageable sessions.

Track Due Dates

This feature is invaluable to Linux users involved in software development and similar projects. You will be able to complete each project milestone before the due date arrives since you will be familiar with the milestone objectives and how they should be pursued.

Manage Your Availability

Let us assume you are a freelance Linux administrator who is already working on a client project to remotely configure and set up a web server on their systems. You then receive an invitation from another client to work on a similar remote system configuration task.

By scheduling and managing your availability, you will know which tasks you have in queue and when you will finish them and thereafter become more efficient.
