CALENDAR(1) CALENDAR(1)
NAME
calendar - reminder service
SYNOPSIS
calendar [ - ] [ n ]
DESCRIPTION
Calendar consults calendar files and prints out lines that
contain today's date or any date up through the nth working
day hence (n=1 by default). Most American-style month-day
dates such as `Dec. 7,' `december 7,' `12/7,' etc., are rec-
ognized, but not `7/12'. The symbol `*' denotes every month
as in `* 7' or `*/7'. A year may follow the day, as in `Dec
7, 84', `Dec 7 1984', or `12/7/84'.
By default, the program consults the file `calendar' in the
$HOME directory (see sh(1)), or in the current directory if
a home directory is not known. Other calendar files to be
consulted may be specified by lines of the form
#include "file"
in the calendar file. Includes do not nest.
When the `-' argument is present, calendar reminds all users
of their calendar engagements by mail(1). Normally this hap-
pens daily in the wee hours under control of cron(8). Calen-
dars not in home directories, or recipients not registered
as users, may be registered for reminder service by placing
lines of the form `pathname mailname' in file
/usr/lib/calendar.

BUGS
The mail reminder service doesn't work when it finds less
than two calendars.
Your calendar must be public information for you to get
reminder service.
Holidays are what the program says they are.
