Cron expression tester › * * * * *
What does * * * * * mean?
Every minute. Runs once every minute, 60 times an hour, all day every day.
The most frequent standard cron interval. Common for tight health checks, queue workers, and near-real-time polling — but be careful: a job on this schedule that overruns a minute can stack up.

Field-by-field breakdown
| Value | Field | Meaning |
|---|---|---|
* | Minute (0–59) | every value |
* | Hour (0–23) | every value |
* | Day of month (1–31) | every value |
* | Month (1–12) | every value |
* | Day of week (0–6, Sun=0) | every value |
Standard 5-field Vixie/POSIX cron: minute hour day-of-month month day-of-week. Cron uses the server's local timezone unless configured otherwise. Non-standard extensions (@daily, L, W, #, seconds) aren't evaluated here.

Will you know if a every minute run is skipped?
Knowing when * * * * * should fire is only half of it. The failure that hurts is the silent one — the box was asleep, the trigger broke, the token expired, and nobody noticed. Cronpulse is a free dead-man's-switch: your job pings a URL each time it runs on this schedule, and if a ping goes missing, we alert you by email, Discord, Slack, or webhook.
