Cron Expression Generator
Build any cron schedule visually and get the correct expression instantly
*/15 * * * *Build cron expressions visually without memorising the syntax. Select your schedule (every 5 minutes, every Monday at 9am, the first day of each month) and get the correct cron string ready to paste into your server, Make scenario, or CI/CD pipeline.
Cron Expression Format
A cron expression has five fields:
* * * * *
│ │ │ │ └── Day of week (0-7, 0 and 7 = Sunday)
│ │ │ └──── Month (1-12)
│ │ └────── Day of month (1-31)
│ └──────── Hour (0-23)
└────────── Minute (0-59)Common Cron Examples
| Schedule | Cron Expression |
|---|---|
| Every minute | * * * * * |
| Every 5 minutes | */5 * * * * |
| Every day at 9am | 0 9 * * * |
| Every Monday at 9am | 0 9 * * 1 |
| First day of month at midnight | 0 0 1 * * |
| Every weekday at 8am | 0 8 * * 1-5 |
| Every 6 hours | 0 */6 * * * |
Where Cron Expressions Are Used
- Linux/Unix — crontab for scheduled scripts
- GitHub Actions —
schedule.cronin workflow YAML - AWS Lambda — EventBridge scheduled rules
- Make/n8n — scenario scheduling
- Kubernetes — CronJob resources
- Heroku/Railway — scheduler add-ons
This comes up regularly in n8n and Make.com scheduled scenarios — n8n Self-Hosted Setup covers setting up scheduled backup jobs on your own instance, and Make.com Data Store Tutorial covers building scheduled sync jobs that track their own last-run timestamp.
Beyond Scheduling
Cron is great for simple recurring tasks. For complex workflows with conditions, retries, and dependencies, consider a dedicated scheduler like Temporal, Celery Beat, or a cron-triggered automation in Make. Book a consultation if your scheduled jobs are getting complex.
