Understanding Cron Schedules by Example

Cron expressions can feel cryptic at first glance, but they follow a logical pattern once you understand the five fields: minute, hour, day of month, month, and day of week. The examples below cover the most common scheduling scenarios you will encounter as a developer, system administrator, or DevOps engineer.

Each example includes the full cron expression, a plain-English description, a detailed field breakdown, practical use cases, and platform-specific instructions for Linux, Kubernetes, Docker, and CI/CD systems. Whether you need a job that runs every 5 minutes for cache refreshes or a monthly billing report on the 1st, you will find a ready-to-use expression here.

The examples are organized by frequency: from sub-hourly schedules (every minute through every 30 minutes), to hourly and multi-hour intervals, daily schedules, weekly patterns, and monthly/yearly cadences. Click any card to see the full breakdown with copy-ready syntax for your platform.
