How to format holiday file?

To format a holiday file for use with the ncal command, follow these guidelines:

1. File Format: Each line in the holiday file should represent a single holiday and should be structured as follows:

   Month Day Holiday Name

   • Month: The month number (1 for January, 2 for February, ..., 12 for December).
   • Day: The day of the month (1 to 31).
   • Holiday Name: A descriptive name for the holiday.

2. Example: Here’s an example of how the contents of a holiday file might look:

   # Format: Month Day Holiday Name
   1 1 New Year's Day
   2 14 Valentine's Day
   7 4 Independence Day
   11 11 Veterans Day
   12 25 Christmas Day

3. Comments: You can add comments in the file by starting a line with the # character. These lines will be ignored by ncal.

4. Whitespace: Ensure that there is at least one space between the month, day, and holiday name. Extra spaces are allowed but should not affect the formatting.

5. Save the File: After formatting the file, save it with a .txt extension or any name you prefer.

Once your holiday file is formatted correctly, you can use it with the ncal command by specifying the file with the -h option:

ncal -h ~/path/to/your/holidays.txt

This will display the calendar along with the holidays you defined.
