What is a cron expression?

A cron expression is a string of 5 space-separated fields: minute hour day-of-month month day-of-week. Each field controls when the job runs. Cron jobs use these to run tasks automatically at specified times on Unix/Linux systems, GitHub Actions, Kubernetes, and most schedulers.

Special characters: * / , -

* every value — */n every nth — , list (1,3,5) — - range (9-17)

Day of week numbering

0=Sun, 1=Mon, 2=Tue, 3=Wed, 4=Thu, 5=Fri, 6=Sat. Some systems accept 7=Sun. Three-letter abbreviations (SUN, MON...) work in many implementations.
