Frequently Asked Questions
FAQs about Crontab Generator
What does * mean in a cron field?
An asterisk (*) means "any value". For example, * in the minute field means the job runs every minute.
How do I run a job every 5 minutes?
Use */5 in the minute field and * for all other fields: */5 * * * *
How do I run a job at 2:30 AM every day?
Set minute to 30, hour to 2, and all other fields to *: 30 2 * * *
What is the difference between day-of-month and day-of-week?
Day-of-month (1–31) runs the job on a specific calendar date. Day-of-week (0–6, where 0 is Sunday) runs the job on specific weekdays. If both are set, the job runs when either condition is met.
Does this work with GitHub Actions cron schedules?
Yes. GitHub Actions uses standard 5-field cron syntax (without seconds), which is exactly what this tool generates.
