Cron Every Minute

The cron expression * * * * * is the simplest possible schedule — it triggers a job every single minute, 24 hours a day, 7 days a week. Each asterisk represents a wildcard for one of the five cron fields: minute, hour, day of month, month, and day of week.

This is commonly used for health checks, queue processing, real-time data syncing, and monitoring scripts that need to run continuously. Because it fires 1,440 times per day, make sure your job completes in well under 60 seconds to avoid overlapping executions.

If every minute is too frequent, consider */5 * * * * (every 5 minutes) or */15 * * * * (every 15 minutes) for less intensive polling.
