About * * * * *
* * * * * matches every minute of every hour, so the job starts 60 times an hour — the finest granularity standard cron offers. Anything faster needs two lines with sleep, or a scheduler with a seconds field; the FAQ on the home page covers both.
Cron reads the five fields as minute hour day month weekday. For this schedule that breaks down as:
| Field | Position | Matches |
|---|---|---|
* | minute | every minute |
* | hour | every hour |
* | day of month | every day |
* | month | every month |
* | day of week | every day of the week |

Use it in crontab or GitHub Actions
Both snippets are ready to paste. A crontab runs in the server's local timezone; GitHub Actions always evaluates schedules in UTC. For Kubernetes, AWS EventBridge, or Vercel, use the export menu in the calculator above.
