21_Calendar/README.md
This program prints out a calendar for any year. You must specify the starting day of the week of the year:
You can determine this by using the program WEEKDAY. You must also make two changes for leap years. The program listing describes the necessary changes. Running the program produces a nice 12-month calendar.
The program was written by Geoffrey Chase of the Abbey, Portsmouth, Rhode Island.

While many modern environments have time/date functions that would make this program both easier and more automatic, in these ports we are choosing to do without them, as in the original program.
Some ports choose to ask the user the starting day of week, and whether it's a leap year, rather than force changes to the code to fit the desired year.
