MY_CALENDAR\ Simple calendar reminder utility {#my_calendar-simple-calendar-reminder-utility align=”center”} ================================

MY_CALENDAR is a C++ program which carries out a simple calendar reminder service.

It reads the file “calendar” stored in the user’s home directory. It prints every line that contains a string suggesting today’s date, or “nearby” dates. On Sunday through Thursday, a nearby date is today or tomorrow. On Friday and Saturday a nearby date includes today through Monday. Most reasonable combinations of dates are recognized.

Some things happen every Monday or Thursday, and it is natural to record in your calendar file a single entry that reads:

        Mondays - Pay blackmailer

MY_CALENDAR will recognize such a line, and print it every Monday, ensuring prompt payment.
