The "value too great for base" happens because there is a number with a leading zero, and bash assumes octal, and 8 is too high for an octal number.
It happens with
Code:
day=$((day+1))
or later with month.
As always there is an escape from such (mis)feature: a 10# prefix forces a base10=decimal
Code:
day=$((10#$day+1))
month=$((10#$month))
Now the leading zero are removed.

You certainly want
Code:
if [ \( $year4 -eq 0 -a \
$year100 -ne 0 \) -o \
$year400 -eq 0 ]
then
declare -a max_month=(0 31 29 31 30 31 30 31 31)
fi
As Jim said, such calculations are error prone.
perl is safer because it uses the libc routines.
Thanks madeingermany...I tried but the error is still because of line I mentioned in my first post n I am using AIX so most of the commands don't work...I need to do date calculation for an arbitrary date so tz doesn't work for me either

html::formhandler::field::date
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"
