Not portable. Assigning the same variable twice in the same statement has
different order of operations in some shells. Use:
month=$(date +%m); month=${month#0}
instead.

Not true. You can do it via POSIX and without a loop by using an
intermediate variable:
foo=00081
bar=${foo%%[!0]*}
foo=${foo#$bar}}
