What is a cron expression?
A cron expression is a string of five fields that tells a scheduler when to run a
job: minute, hour, day of month,
month, and day of week. Each field accepts a
value, a list (1,15), a range (1-5), a step
(*/10), or * for "every".

Will you know if this job silently fails?
Cron jobs fail quietly — a server reboots, a path changes, or an error code is ignored — and nobody notices until the data is missing. A cron monitor (a dead-man’s-switch) alerts you when a scheduled job does not check in on time.
