How to show next month?

To display the calendar for the next month using the ncal command, you can use the -M option along with the -A option to specify how many months ahead you want to see. Here's how you can do it:

ncal -A 1

This command will show the calendar for the next month. If you want to see the current month along with the next month, you can use:

ncal -A 1 -B 1

This will display the current month and the next month together.
