This line:
DAY= date | cut -f 1 -d ' '
does not set the variable DAY to anything. It is basicly the same as:
date | cut -f 1 -d ' '

And then the next line just prints an empty $DAY variable.

You want something like:
DAY=`date | cut -f 1 -d ' '`

Next time please tell which shell you are using. Also which version of unix.

NAME
calendar - reminder service SYNOPSIS
DESCRIPTION
consults the file in the current directory and prints out lines containing today's or tomorrow's date anywhere in the line. On weekends, ``tomorrow'' extends through Monday. When a command-line argument is present, searches for the file in each user's home directory, and sends any positive results to the user by (see mail(1)). Normally this is done daily in the early morning hours under the control of (see cron(1M)). When invoked by reads the first line in the file to determine the user's environment. Language-dependent information such as spelling and date format (described below) are determined by the user-specified statement in the file. This statement should be of the form where language is a valid language name (see lang(5)). If this line is not in the file, the action described in the section is taken. is concerned with two fields: month and day. A month field can be expressed in three different formats: a string representing the name of the month (either fully spelled out or abbreviated), a numeric month, or an asterisk (representing any month). If the month is expressed as a string representing the name of the month, the first character can be either upper-case or lower-case; other characters must be lower- case. The spelling of a month name should match the string returned by calling (see nl_langinfo(3C)). The day field is a numeric value for the day of the month. Month-Day Formats If the month field is a string, it can be followed by zero or more blanks. If the month field is numeric, it must be followed by either a slash or a hyphen If the month field is an asterisk it must be followed by a slash The day field can be followed immediately by a blank or non-digit character. Day-Month Formats The day field is expressed as a numeral. What follows the day field is determined by the format of the month. If the month field is a string, the day field must be followed by zero or one dot followed by zero or more blanks. If the month field is a numeral, the day field must be followed by either a slash or a hyphen If the month field is an asterisk, the day field must be followed by a slash EXTERNAL INFLUENCES

If is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty vari- able. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5). International Code Set Support Single- and multi-byte character code sets are supported. EXAMPLES

To get reminder service, either your calendar must be public information or you must run from your personal file, independent of any run systemwide. Note that if you run yourself, the calendar file need not reside in your home directory. extended idea of ``tomorrow'' does not account for holidays. This command is likely to be withdrawn from X/Open standards. Applications using this command might not be portable to other vendors' platforms. AUTHOR
