About cron expressions

Cron expressions define when a task runs: minute, hour, day of month, month, and day of week. Use this builder to create expressions for crontab, GitHub Actions, or other schedulers without memorizing the syntax.

Frequently asked questions

What cron format does this builder use?

Standard 5-field cron: minute (0–59), hour (0–23), day of month (1–31), month (1–12), day of week (0–6, 0=Sunday).

Can I use steps like */5 for every 5 minutes?

Yes. In Custom mode, use */5 in the Minutes field for every 5 minutes, or */15 for every 15 minutes. Same pattern works for other fields.

Where can I parse an existing cron expression?

Use our Cron Expression Parser tool to paste an expression and see its summary and next run times.
