## NAME

## SYNOPSIS

## DESCRIPTION

The

utility checks the current directory or the directory specified by the

environment variable for a file named

and displays lines that begin with either today's date or tomorrow's. On Fridays, events on Friday through Monday are displayed.

The options are as follows:

Print lines from today and next

days (forward, future). Defaults to one. (same as -l)

Process the

files of all users and mail the results to them. This requires superuser privileges.

Print lines from today and previous

days (backward, past).

Enforce special date calculation mode for KOI8 calendars.

Print lines from today and next

days (forward, future). Defaults to one. (same as -A)

Print lines from today and next

days, only if today is Friday (forward, future). Defaults to two, which causes

to print entries through the weekend on Fridays.

Use

as the default calendar file.

Act like the specified value is

instead of using the current date. If yy is specified, but cc is not, a value for yy between 69 and 99 results in a cc value of 19. Otherwise, a cc value of 20 is used.

To handle calendars in your national code table you can specify

in the calendar file as early as possible. To handle national Easter names in the calendars,

(for Catholic Easter) or

(for Orthodox Easter) can be used.

A special locale name exists:

Specifying

indicates that the dates will be read using the C locale, and the descriptions will be encoded in UTF-8. This is usually used for the distributed calendar files. The

variable can be used to specify the style. Only

and

styles are currently supported. Use

to return to the default (Gregorian).

To enforce special date calculation mode for Cyrillic calendars you should specify

and

where <local_name> can be ru_RU.KOI8-R, uk_UA.KOI8-U or by_BY.KOI8-B.

Note that the locale is reset to the user's default for each new file that is read. This is so that locales from one file do not accidentally carry over into another file.

Other lines should begin with a month and day. They may be entered in almost any format, either numeric or as character strings. If proper locale is set, national months and weekdays names can be used. A single asterisk (`*') matches every month. 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 multiple line specifications for a single date.

(may be followed by a positive or negative integer) is Easter for this year.

(may be followed by a positive or negative integer) is Orthodox Easter for this year. Weekdays may be followed by

(aliases last, first, second, third, fourth) for moving events like

By convention, dates followed by an asterisk

are not fixed, i.e., change from year to year.

Day descriptions start after the first <tab> character in the line; if the line does not contain a <tab> character, it isn't printed out. If the first character in the line is a <tab> character, it is treated as the continuation of the previous description.

The calendar file is preprocessed by

allowing the inclusion of shared files such as company holidays or meetings. If the shared file is not referenced by a full pathname,

searches in the current (or home) directory first, and then in the directory directory

and finally in

Empty lines and lines protected by the C commenting syntax

are ignored.

Some possible calendar entries (a et sequence denotes a <tab> character):

## SEE ALSO

## STANDARDS

The

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 at the beginning of a line.

## COMPATIBILITY

The

command will only display lines that use a <tab> character to separate the date and description, or that begin with a <tab>. This is different than in previous releases.

The

flag argument syntax is from the original FreeBSD

program.

The

and

flags are Debian-specific enhancements. Also, the original

program did not accept

as an argument to the

flag.

Using

as a locale name is a Debian-specific enhancement.
