Most likely the reason is (from man 5 crontab)
Quote:
The day of a command's execution can be specified by two fields — day of month, and day of week. If both fields are restricted (ie, aren't *), the command will be run when either field matches the current time. For example, "30 4 1,15 * 5" would cause a command to be run at 4:30 am on the 1st and 15th of each month, plus every Friday.

that is the day fields are addictive, but one does not exclude the other. Your best bet is to modify the script (if possible) by adding a date check at the very beginning. For example, suppose your crontab is simply
Code:
50 16 8-14 * * /home/user/script.sh
then your script should begin with:
Code:
#!/bin/bash
[ $(date +%u) -ne 1 ] && exit
Hope this helps.
