Quick and painless crontab question

[skydiverQ]

Hi there, tia for your help

I'll make try to make this as simple as possible...I think it's an easy one but I cannot locate an answer anywhere!

I have a job that I want to run every minute between the hours of 9am and 9pm. I'm just confused as to how I'd note the hours, I know it's going to be one of the following:

* 9-21 * * * /usr/local/myscript.pl

-OR-

* 9-20 * * * /usr/local/myscript.pl

If I include the 21 in the hour range, will it then run every hour INCLUDING 21:00? That is, run at 21:00, 21:01, 21:02 etc. until 21:59?

I want it to not run before 9am, not run later than 9pm. Get it? thanks!
