I have a script that gives a error in BASH whenever I try to add 01-09

X=$((X+1))

line 42: 09: value too great for base (error token is "09")

This is caused by a date command variable and I'm trying to avoid
having to make other changes in the script.

Numbers beginning with 0 are taken as octal. With date number it is
easy to remove leading digits:

X=09
X=$(( ${X#0} + 1 ))
