Cron: Every minute (* * * * *)

The cron expression * * * * * translates to “Every minute”. It is one of the most commonly used schedules (every minute).

Every field is a wildcard, so there is nothing to constrain the schedule - the job fires at the top of every single minute, 60 times an hour, 1,440 times a day. This is the most frequent standard cron schedule (you cannot go below one minute without a different scheduler). Use it for near-real-time polling, health checks or queue draining, but be careful: if one run can take longer than a minute, overlapping executions can pile up unless your job guards against it.
