Frequently Asked Questions

What do the five cron fields mean?

In order: minute (0–59), hour (0–23), day of month (1–31), month (1–12) and day of week (0–6, Sunday is 0). An asterisk means every value.

How do I run something every 15 minutes?

*/15 * * * * — the step syntax means every 15th minute starting from zero, so it fires at :00, :15, :30 and :45.

What happens if I set both day of month and day of week?

Standard cron treats them as OR, not AND. "0 0 1 * 1" runs on the 1st of the month *and* every Monday. This trips people up constantly, so the description spells it out.

Which time zone does cron use?

The system time zone of the machine running it, unless your scheduler lets you set one. That matters for daylight saving: a job at 02:30 may run twice or not at all on transition days.
