Odd and even date in bash

Hi All,

I'm having the following script:

Code:
#!/bin/bash

date=$(date +%d)

echo $date

if [ ${date%2} -eq 0 ];

then

echo 'date is even'

else

echo 'date is odd'

fi

but I can not find out why it's not working.Example:

Code:
cat test_even.sh 
#!/bin/bash

date=$(date +%d)

echo $date

if [ ${date%2} -eq 0 ];

then

echo 'date is even'

else

echo 'date is odd'

fi

Code:
~ $ . test_even.sh 
08
date is odd

 $ date
Fri Nov  8 15:08:18 EET 2013

Please advise,thanks

px_date2string - Converts a date into a string.

SYNOPSIS
string px_date2string (resource $pxdoc, int $value, string $format) DESCRIPTION
Turns a date as it stored in the paradox file into human readable format. Paradox dates are the number of days since 1.1.0000. This func- tion is just for convenience. It can be easily replaced by some math and the calendar functions as demonstrated in the example below. PARAMETERS
o $pxdoc - Resource identifier of the paradox database as returned by px_new(3). o $value - Value as stored in paradox database field of type PX_FIELD_DATE. o $format - String format similar to the format used by date(3). The placeholders support by this function is a subset of those supported by date(3) (Y, y, m, n, d, j, L). RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Turn a paradox date into a human readable form <?php $px = px_new(); /* make up a date as it could be stored in */ /* a date field of a paradox db. */ /* 700000 days since 1.1.0000. */ $days = 700000; /* Use the calendar functions to print a */ /* human readable format of the date */ echo jdtogregorian($days+1721425)." "; /* px_date2string() outputs the same */ echo px_date2string($px, $days, "n/d/Y")." "; px_delete($px); ?> The above example will output: 7/15/1917 7/15/1917 SEE ALSO
