bash month variable

I would like to execute some bash script ten months during the year, just not July or August. So, I tried to capture the month number and would compare latter, but it doesn't work.

For example:

declare -i mon='date +%m'
echo $mon

Produces an error.
-bash: declare: date +%m: syntax error: operand expected (error token is "%m")

Oh, there must be a better way. Thanks in advance....

Just use this (note the backticks):
mon=`date +%m`

If you are running from cron then you can also specify the months to run in field 4:
man crontab
