CALENDAR(1)

NAME
calendar - reminder service

SYNOPSIS
calendar [-]

DESCRIPTION
Calendar consults the file `calendar' in the current directory and prints out lines that contain today's or tomorrow's date anywhere in the line. In the C locale, most reasonable month-day dates such as `Dec. 7,' `december 7,' `12/7,' etc., are recognized, but not `7 December' or `7/12'. On weekends `tomorrow' extends through Monday.

When an argument is present, calendar does its job for every user who has a file `calendar' in his login directory and sends him any positive results by mail(1). This can be done daily in the wee hours under control of cron(1).

ENVIRONMENT VARIABLES

LANG, LC_ALL
    See locale(7).

LC_CTYPE
    Used to separate the first three characters for abbreviated month names.

LC_TIME

NOTES

Calendar's extended idea of `tomorrow' doesn't account for holidays.
