Frequently Asked Questions

What do the five cron fields mean?

Minute (0–59), hour (0–23), day of month (1–31), month (1–12 or JAN–DEC) and day of week (0–7 or SUN–SAT, where 0 and 7 are Sunday). A sixth field at the front, if present, is seconds.

How do I run a cron job every 5 minutes?

Use */5 * * * *. The */5 step means every fifth minute starting at 0: :00, :05, :10 and so on.

What happens when both day-of-month and day-of-week are set?

In standard (Vixie) cron the job runs when either one matches. For example, 0 0 1 * MON runs at midnight on the 1st of every month and on every Monday.

Which timezone does cron use?

The timezone of the machine or service running it, often UTC on servers. Pick Local or UTC here to see run times either way.
