The "jcal" command is used to display the Julian calendar in the terminal.

The Julian calendar is an ancient calendar system that was introduced by Julius Caesar in 45 BCE. It was widely used until it was replaced by the Gregorian calendar in the late 16th century.

When you run the "jcal" command, it will display the current month's calendar with each day represented by a number. It also provides information about the day of the week and key events or holidays that may take place during that month. By scrolling through the output, you can view the calendar for different months and years.

The "jcal" command is primarily used in Unix-based systems and is available in various Linux distributions. It allows users to quickly check and reference the Julian calendar directly from the terminal without the need for a dedicated calendar application.
