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
or later with month.
As always there is an escape from such (mis)feature: a 10# prefix forces a base10=decimal

As Jim said, such calculations are error prone.
perl is safer because it uses the libc routines.

chewmail - mail archiver
SYNOPSIS
chewmail [OPTIONS] <MAILBOX> ...
DESCRIPTION
chewmail is a program for archiving mail. It is inspired by the by the Python-based archivemail, but with more useful semantics. All mail
is archived to the mailbox specified with the --output-box switch, in mbox format. It can read mailboxes in mbox, Maildir and MH formats.
Internally, chewmail uses Mail::Box, so it support file names and URLs supported by that module.
OPTIONS -o mailbox-format, --output-box=mailbox-format
The mailbox to archive messages to. The mailbox is run through the Date::Format module, so it supports all it's conversion specifiers.
The date and time is relative to the messages timestamp, or the current time if the timestamp is impossible to determine. A sample of
the conversion specifiers follows:
%% PERCENT
%b month abbr
%B month
%d numeric day of the month, with leading zeros (eg 01..31)
%e numeric day of the month, without leading zeros (eg 1..31)
%D MM/DD/YY
%G GPS week number (weeks since January 6, 1980)
%h month abbr
%H hour, 24 hour clock, leading 0's)
%I hour, 12 hour clock, leading 0's)
%j day of the year
%k hour
%l hour, 12 hour clock
%L month number, starting with 1
%m month number, starting with 01
%n NEWLINE
%o ornate day of month -- "1st", "2nd", "25th", etc.
%t TAB
%U week number, Sunday as first day of week
%w day of the week, numerically, Sunday == 0
%W week number, Monday as first day of week
%x date format: 11/19/94
%y year (2 digits)
%Y year (4 digits)
-d days-old, --days=days-old
Only archive messages older than than this many days.
-D date, --date=date
Only archive messages old than this date. The date can be any date understood by Perl's Date::Parse module.
-R, --only-read
Only archive messages that are marked seen or read.
--delete-immediately
Synchonize the mailboxes after every message is moved. This will be substantially slower but may provide better recovery for some mail-
box formats in the event of a crash.
--preserve-timestamp
Preserve the atime and mtime of the input mailbox. This only affects file-based mailboxes, such as mbox.
-n, --dry-run
Go through all the motions of archiving the mail, but don't actually change any mailboxes.
-v, --verbose
Output more informational messages. Use multiple times for more verbosity.
-q, --quiet
Don't output any messages other than error messages.
-V, --version
Print the version number then exit.
-h, --help
Print usage information then exit.
EXAMPLES
Archive two day old messages in inbox to inbox-old:
chewmail --days 2 -o inbox-old inbox
Archive read messages to a mailbox named the year-month of the message:
chewmail --only-read -o %Y-%m inbox
