Frequently Asked Questions

What is a cron expression? +

A cron expression is a string used to define schedules for automated tasks (cron jobs). It has 5 fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-7). For example, "0 9 * * 1" means "every Monday at 9:00 AM".

What does * (asterisk) mean in a cron expression? +

* means "every" for that field. "* * * * *" means "every minute of every hour of every day". You can use */n for intervals — "*/15 * * * *" means "every 15 minutes".

What is the difference between day of month and day of week? +

Day of month (field 3) schedules tasks on specific dates like the 1st or 15th. Day of week (field 5) schedules on specific days like Monday or Friday. Using both fields in the same expression means "on this date OR this weekday" (OR, not AND).

How do I run a cron job every 5 minutes? +

Use "*/5 * * * *" — the */5 in the minute field means "every 5 minutes". Similarly, "*/30 * * * *" runs every 30 minutes, and "0 */2 * * *" runs every 2 hours at the top of the hour.

Can I test if my cron expression is correct? +

Yes — this generator shows a human-readable description of your cron expression in real-time, so you can immediately see if your schedule matches your intention before adding it to your server.
