[SOLVED] this crontab schedule incorrectly ran today

hi, this ran on friday the 13th as expected; it didnt run on saturday or sunday (good); but it ran this morning which is wrong.

Code:

[schneidz@hyper ~]$ uname -a -m -p
Linux hyper 2.6.32-696.23.1.el6.x86_64 #1 SMP Sat Feb 10 11:10:31 EST 2018 x86_64 x86_64 x86_64 GNU/Linux
[schneidz@hyper ~]$ crontab -l
30 4 13 4 1-5 /users/schneidz/bin/hello-world.ksh

does the 5th field override the 3rd field ?

One of the more common mistakes with cron is if the day of month or day of week match i.e. it will run when either field matches. Your cron job will run Monday-Friday regardless of the day of month.
