Pass the value from pipe

am trying to pass the date calculated to variable so that i can use the same for my further reporting and tracking of the changes as per the variable value.

System = SunOS
Release = 5.9
KernelID = Generic_122300-61

Code:

date '+%m %d %Y' |
{
read MONTH DAY YEAR
DAY=`expr "$DAY" - 1`
case "$DAY" in
        0)
                MONTH=`expr "$MONTH" - 1`
                        case "$MONTH" in
                                0)
                                        MONTH=12
                                        YEAR=`expr "$YEAR" -1`
                                ;;
                        esac
                DAY=`cal $MONTH $YEAR | grep . | fmt -1 | tail -1`
esac
vardt=$?
if [ $vardt -ne 0 ];then
        echo "ERROR DURING SPOOLING PREVIOUS DAY DATE."
        exit 1
fi
YESTERDAY=${MONTH}/${DAY}/${YEAR};export YESTERDAY
} | YDAY=${YESTERDAY};export YDAY
echo $YDAY

OUTPUT in debug mode

Code:

+ date +%m %d %Y
+ read MONTH DAY YEAR
YDAY=
+ export YDAY
+ echo
+ expr 05 - 1
DAY=4
vardt=0
+ [ 0 -ne 0 ]
YESTERDAY=04/4/2015
+ export YESTERDAY

Request to help me please and thanks in advance.

column

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME

     column -- columnate lists

SYNOPSIS

     column [-tx] [-c columns] [-s sep] [file ...]

DESCRIPTION

     The column utility formats its input into multiple columns.  Rows are filled before columns.  Input is taken from file operands, or, by
     default, from the standard input.	Empty lines are ignored.

     The options are as follows:

     -c      Output is formatted for a display columns wide.

     -s      Specify a set of characters to be used to delimit columns for the -t option.

     -t      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by default, or with
	     the characters supplied using the -s option.  Useful for pretty-printing displays.

     -x      Fill columns before filling rows.

     Column exits 0 on success, >0 if an error occurred.

ENVIRONMENT

     COLUMNS  The environment variable COLUMNS is used to determine the size of the screen if no other information is available.

EXAMPLES

	   (printf "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME
" 
	   ; ls -l | sed 1d) | column -t
