calendar - reminder service SYNOPSIS
calendar [-] DESCRIPTION
The calendar utility consults the file calendar in the current directory and writes lines that contain today's or tomorrow's date anywhere in the line to standard output. Most reasonable month-day dates such as Aug. 24, august 24, 8/24, and so forth, are recognized, but not 24 August or 24/8. On Fridays and weekends "tomorrow" extends through Monday. calendar can be invoked regularly by using the crontab(1) or at(1) commands. When the optional argument - is present, calendar does its job for every user who has a file calendar in his or her login directory and sends them any positive results by mail(1). Normally this is done daily by facilities in the UNIX operating system (seecron(1M)). If the environment variable DATEMSK is set, calendar will use its value as the full path name of a template file containing format strings. The strings consist of conversion specifications and text characters and are used to provide a richer set of allowable date formats in dif- ferent languages by appropriate settings of the environment variable LANG or LC_TIME; see environ(5). Seestrftime(3C) for the list of allowable conversion specifications. EXAMPLES
Example 1: Possible contents of a template The following example shows the possible contents of a template: %B %eth of the year %Y %B represents the full month name, %e the day of month and %Y the year (4 digits). If DATEMSK is set to this template, the following calendar file would be valid: March 7th of the year 1989 <Reminder> ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of calendar: LC_CTYPE, LC_TIME, LC_MES- SAGES, NLSPATH, and TZ. EXIT STATUS
0 Successful completion. >0 An error occurred. FILES

Appropriate lines beginning with white space will not be printed. Your calendar must be public information for you to get reminder service. calendar's extended idea of ``tomorrow'' does not account for holidays. The - argument works only on calendar files that are local to the machine; calendar is intended not to work on calendar files that are mounted remotely with NFS. Thus, `calendar -' should be run only on diskful machines where home directories exist; running it on a disk- less client has no effect. calendar is no longer in the default root crontab. Because of the network burden `calendar -' can induce, it is inadvisable in an environ- ment running ypbind(1M) with a large passwd.byname map. If, however, the usefulness of calendar outweighs the network impact, the super- user may run `crontab -e' to edit the root crontab. Otherwise, individual users may wish to use `crontab -e' to edit their own crontabs to have cron invoke calendar without the - argument, piping output to mail addressed to themselves.

CALENDAR(1) BSD General Commands Manual CALENDAR(1) NAME
calendar -- reminder service SYNOPSIS
calendar [-ax] [-d MMDD[[YY]YY]] [-f file] [-l days] [-w days] DESCRIPTION
The calendar utility processes text files and displays lines that match certain dates. The following options are available: -a Process the ``calendar'' files of all users and mail the results to them. This requires super-user privileges. -d MMDD[[YY]YY] Display lines for the given date. By default, the current date is used. The year, which may be given in either two or four digit format, is used only for purposes of determining whether the given date falls on a Friday in that year (see below). If the year is not specified, the current year is assumed. -f file Display matching calendar files from the given filename. By default, the following filenames are checked for: ~/calendar ~/.calendar /etc/calendar and the first which is found is used. The filename may be absolute. If not absolute, it is taken relative to the directory speci- fied by the CALENDAR_DIR environment variable, if set; otherwise, it is taken relative to the user's home directory. Or, if the -a flag is given, a non-absolute filename is taken relative to each user's home directory in turn. -l days Causes the program to ``look ahead'' a given number of days (default one) from the specified date and display their entries as well. -w days Causes the program to add the specified number of days to the ``look ahead'' number if and only if the day specified is a Friday. The default value is two, which causes calendar to print entries through the weekend on Fridays. -x Causes calendar not to set the CPP_RESTRICTED environment variable. Passing this flag allows users the (somewhat obscure) option of including a named pipe via cpp(1)'s #include syntax, but opens up the possibility of calendar hanging indefinitely if users do so incorrectly. For this reason, the -x flag should never be used with calendar -a. Lines should begin with a month and day. They may be entered in almost any format, either numeric or as character strings. A single aster- isk ('*') matches every month, or every day if a month has been provided. This means that two asterisks ('**') matches every day of the year, and is thus useful for ToDo tasks. A day without a month matches that day of every week. A month without a day matches the first of that month. Two numbers default to the month followed by the day. Lines with leading tabs default to the last entered date, allowing multi- ple line specifications for a single date. By convention, dates followed by an asterisk are not fixed, i.e., change from year to year. The ``calendar'' file is preprocessed by cpp(1), allowing the inclusion of shared files such as company holidays or meetings. If the shared file is not referenced by a full pathname, cpp(1) searches in the current (or home) directory first, and then in the directory /usr/share/calendar. Empty lines and lines protected by the C commenting syntax (/* ... */) are ignored. Some possible calendar entries: #include <calendar.usholiday> #include <calendar.birthday> 6/15 ... June 15 (if ambiguous, will default to month/day). Jun. 15 ... June 15. 15 June ... June 15. Thursday ... Every Thursday. June ... Every June 1st. 15 * ... 15th of every month. *15 ... 15th of every month. June* ... Every day of June. ** ... Every day FILES
The following default calendar files are provided: calendar.birthday Births and deaths of famous (and not-so-famous) people. calendar.christian Christian holidays. This calendar should be updated yearly by the local system administrator so that roving holidays are set correctly for the current year. calendar.computer Days of special significance to computer people. calendar.history Everything else, mostly U.S. historical events. calendar.holiday Other holidays, including the not-well-known, obscure, and really obscure. calendar.judaic Jewish holidays. This calendar should be updated yearly by the local system administrator so that roving holidays are set correctly for the current year. calendar.lotr Important dates in the Lord of the Rings series. calendar.music Musical events, births, and deaths. Strongly oriented toward rock 'n' roll. calendar.netbsd Important dates in the history of the NetBSD project. Mostly releases and port additions. calendar.usholiday U.S. holidays. This calendar should be updated yearly by the local system administrator so that roving holidays are set correctly for the current year. COMPATIBILITY
The calendar program previously selected lines which had the correct date anywhere in the line. This is no longer true, the date is only recognized when it occurs first on the line. In NetBSD 3.0, the calendar command was modified to search the user's home directory instead of the current directory by default. Users desiring the historical behavior should set the CALENDAR_DIR environment variable to ., or use the -f flag. SEE ALSO

A calendar command appeared in Version 7 AT&T UNIX. BUGS
calendar doesn't handle events that move around from year to year, i.e., ``the last Monday in April''. The -a option ignores the user's CALENDAR_DIR environment variable. BSD
