Here, "${year}" is a placeholder for a variable that should be replaced with the desired year when executing the command. For example, if you want to display the calendar for the year 2022, you would replace "${year}" with "2022".
When the command is executed with the appropriate value for the year variable, it will generate and display a calendar for that specific year. The calendar typically includes the months, days, and weeks, highlighting any important dates or holidays.
