Need help with date arithmetic please

Hello fellow forum members,

I wrote below piece of code to calculate the date after a given date -
Code:
date=$DATE_FINAL
declare -a  max_month=(0 31 28 31 30 31 30 31 31 30 31 30 31)
eval $(echo $date|sed 's!\(....\)\(..\)\(..\)!year=\1;month=\2;day=\3!')
(( year4=year%4 ))
(( year100=year%100 ))
(( year400=year%400 ))
if [ \( $year4 -eq 0 -a \
        $year100 -ne 0 \) -o \
     $year400 -eq 0 ]
then
declare -a  max_month=(0 31 28 31 30 31 30 31 31 30 31 30 31)
fi
day=$((day+1))
if [ $day -gt ${max_month[$month]} ] >| /wload/baot/home/baoted9/logs_bde27_conversion_1/ataa_display.logs 2>&1
then
  day=1
  month=$((month+1))
  if [ $month -gt 12 ]
  then
    year=$((year+1))
    month=1
  fi
fi
if [ $month -eq "08" ] ||  [ $month -eq "09" ]
then
future_date_final=$(echo $year"$month"$day)
else
future_date_final=$(printf "%4.4d%2.2d%2.2d" $year $month $day)
fi
echo "this is your final business date $future_date_final"

It calculates the date correctly however throws an error at the end of the code as below -
Code:
line 79: 08: value too great for base (error token is "08")

It just looks too ugly, not sure how to remove it as otherwise code is working fine, tried redirecting it to a log file still appearing.
Also, I am facing issue with below code for a plain cd command with code highlighted in red -
Code:
echo "pset  date $Param_date_1"
cd /wload/baot/home/baotasa0/sandboxes_finance/ext_ukba_bde/pset >| /wload/baot/home/baoted9/logs_bde27_conversion_1/at_display.logs 2>&1
sh UKBA_publish.sh UKBA $Param_date_1 3 >| /wload/baot/home/baoted9/logs_bde27_conversion_1/ate_display.logs 2>&1

Error is -
Code:
./auto2.sh: line 190: syntax error: unexpected end of file

Any leads will be greatly appreciated.

HTML::FormHandler::Field::Date(3pm)			User Contributed Perl Documentation		       HTML::FormHandler::Field::Date(3pm)

NAME
HTML::FormHandler::Field::Date - a date field with formats VERSION
version 0.40013 SUMMARY
This field may be used with the jQuery Datepicker plugin. You can specify the format for the date using jQuery formatDate strings or DateTime strftime formats. (Default format is format => '%Y-%m-%d'.) d - "%e" - day of month (no leading zero) dd - "%d" - day of month (two digit) o - "%{day_of_year}" - day of the year (no leading zeros) oo - "%j" - day of the year (three digit) D - "%a" - day name short DD - "%A" - day name long m - "%{day_of_month" - month of year (no leading zero) mm - "%m" - month of year (two digit) "%m" M - "%b" - month name short MM - "%B" - month name long y - "%y" - year (two digit) yy - "%Y" - year (four digit) @ - "%s" - Unix timestamp (ms since 01/01/1970) For example: has_field 'start_date' => ( type => 'Date', format => "dd/mm/y" ); or has_field 'start_date' => ( type => 'Date', format => "%d/%m/%y" ); You can also set 'date_end' and 'date_start' attributes for validation of the date range. Use iso_8601 formats for these dates ("yyyy-mm- dd"); has_field 'start_date' => ( type => 'Date', date_start => "2009-12-25" ); Customize error messages 'date_early' and 'date_late': has_field 'start_date' => ( type => 'Date, messages => { date_early => 'Pick a later date', date_late => 'Pick an earlier date', } ); If form has 'is_html5' flag active it will render <input type="date" ... /> instead of type="text" AUTHOR
