How to setup a crontab to execute at specific time

How can I set up my crontab to execute X script at 11:59PM every day without emailing me or creating any logs?

Right now my crontab looks something like this

@daily /path/to/


When you do crontab -e, try this:

59 23 * * * /usr/sbin/myscript > /dev/null

That means: At 59 Minutes and 23 Hours on every day (*) on every month on every weekday, execute myscript.

See man crontab for some more info and examples.
