Calendar Programs
Like most people, I need to help keeping tracking of dates. I have trouble with two types of dates: the ones in the future (upcoming events) and the ones in the past.
The cal.pl program is designed to help me. It examines a calendar file and decides whether an event is approaching. It then writes out a warning message. The default format of an entry in this file is
<date> <Event>
For example:
1/27 Wife's Birthday
This causes the program to warn me seven days before my wife’s birthday.
But for some events, I want more advanced warning. So another optional field is added to tell the program to give me that much extra time. The format of this field is +<warn-time >. For example:
1/27 +30 Wife's Birthday
