Frequently Asked Questions

What is a cron expression?

A cron expression is a string of five fields used by the Unix cron daemon to specify a recurring schedule. The fields represent minute, hour, day of month, month, and day of week.

What does */5 mean in cron?

*/5 means 'every 5 units'. In the minute field it means every 5 minutes (0, 5, 10, 15…). In the hour field it means every 5 hours.

How do I run a cron job every day at 9 AM?

Use: 0 9 * * * — minute 0, hour 9, with wildcards for day, month, and weekday.

How do I run a cron job every hour?

Use: 0 * * * * — This runs at minute 0 of every hour. To run every 30 minutes: */30 * * * *

How do I run a cron job every Monday?

Use: 0 9 * * 1 — This runs at 09:00 every Monday. Replace 1 with 0 or 7 for Sunday, 2 for Tuesday, through 6 for Saturday.

At 09:00 every Monday through Friday. The 1-5 in the day-of-week field specifies Monday (1) through Friday (5).
