NAME
calendar - reminder service
SYNOPSIS
calendar [-]
DESCRIPTION
The calendar command is a convenient way of reminding yourself of
important dates or appointments. You need to set up a file called
calendar containing all the necessary details. Then when you call the
calendar command, all lines in the file calendar which contain today's
or tomorrow's date anywhere in the line are printed on standard out-
put.
The calendar command has to be called from the directory that contains
the calendar file. If you would like to be reminded of your appoint-
ments automatically whenever you log in, set up your calendar file in
your home directory and put the calendar command in your .profile
file. Then today's and tomorrow's appointments will be printed on
standard output whenever you log in.
calendar can also be invoked regularly by using the at and crontab
commands.
Dates in the following formats are recognized: Aug. 31, august 31 and
8/31. On Fridays, tomorrow extends through Saturday, Sunday and Mon-
day. This extended idea of tomorrow does not account for holidays. In
other words, if today is the day before a holiday, tomorrow is inter-
preted as usual and includes only the holiday.
OPTIONS
- If the calendar file is in your home directory, you can use the -
option to call the calendar command from any of your directories.
Your appointments are then not written to standard output, but are
sent by mail instead.
Only for the system administrator:
If the system administrator calls calendar with the - option, all
users who have a calendar file in their home directory will be sent
their appointments by mail. This is normally done on a daily basis
by the Reliant UNIX operating system, which informs all users of
appointments noted in the calendar file.

LOCALE
The LCMESSAGES environment variable governs the language in which
message texts are displayed.
The LCTIME environment variable governs the format of date and time
strings.
If LCMESSAGES or LCTIME is undefined or is defined as the null
string, it defaults to the value of LANG. If LANG is likewise unde-
fined or null, the system acts as if it were not internationalized.
If any of the locale variables has an invalid value, the system acts
as if none of the variables were set.
The LCALL environment variable governs the entire locale. LCALL
takes precedence over all the other environment variables which affect
internationalization.
