Cron Job firing every minute for an hour at it's scheduled execution time

I must have done something wrong in crontab, but I don't see what. The entry below is executing demo-off.sh once a MINUTE beginning at 10 and going till 11.

* 10 * * 4,6 /home/username/demo-off.sh 2> /home/username/demo-off.log

Here is cron.log (shortened)

Aug 16 10:00:01 machine-name CROND[20680]: (username) CMD (/home/username/demo-off.sh 2> /home/username/demo-off.log)
Aug 16 10:01:01 machine-name CROND[20813]: (username) CMD (/home/username/demo-off.sh 2> /home/username/demo-off.log)
Aug 16 10:02:01 machine-name CROND[20887]: (username) CMD (/home/username/demo-off.sh 2> /home/username/demo-off.log) ...
Aug 18 10:57:01 machine-name CROND[9690]: (username) CMD (/home/username/demo-off.sh 2> /home/username/demo-off.log)
Aug 18 10:58:01 machine-name CROND[11257]: (username) CMD (/home/username/demo-off.sh 2> /home/username/demo-off.log)
Aug 18 10:59:02 machine-name CROND[13065]: (username) CMD (/home/username/demo-off.sh 2> /home/username/demo-off.log)

Can someone push me in the right direction in terms of what I did wrong?

I don't try to figure it out, I just use the handy-dandy corntab.com cron gui.

It says that sure enough, what you wrote will run every minute starting at 10:00 on Thursday and Saturday.

I suggest you use corntab to get what you really want - if nothing else, it's an easy way to test your cron entries.

Note: No vested interest in corntab, just a satisfied user.
