Can both variables weekday and day be defined at the same time?
https://docs.ansible.com/ansible/latest/collections/ansible/builtin/cron_module.html
If I set day equals to 2 and weekday equals to 2 then it would works at the 2nd day of every month and tuesday every week?
Try it and see 
weekday is the last position of cron (5th position).
monthday is the third position.
0 4 2 * 2 will execute on 2nd day of month and every tuesday.
So yes, you can set both at the same time. If two parameters are conflicting, it is documentated in general.
Thank you for your respond.
Thereโs no chance to try it for I can only read configs and analyze it.
