0 0-6 * * *
The hour range 0-6 covers midnight through 06:00 — seven hourly firings per night. Use this to schedule heavy maintenance, ETL, log archives etc. during the off-peak window.
See the dedicated guide for the full breakdown: Cron every hour.

Paste this into any cron-compatible scheduler (Linux crontab, AWS EventBridge, Vercel cron, Quartz, node-cron, robfig/cron) to run a job every hour overnight (midnight to 06:00).
The editor above shows the next 30+ runs on a calendar in your local timezone, plus a plain-English description. If the calendar matches your intent, the cron is correct.
It uses standard 5-field cron syntax, so yes — Linux crontab, AWS EventBridge (with the additional `?` and year fields), Vercel cron jobs, Quartz Scheduler, node-cron, robfig/cron, and Kubernetes CronJob all accept it. Vercel's free Hobby plan caps the minimum frequency at once-per-day; the Pro plan removes that cap.
Most schedulers will start the new run anyway, leading to overlap. To prevent this, wrap the command with `flock -n /tmp/myjob.lock /path/to/script.sh` on Linux, or set `concurrencyPolicy: Forbid` on Kubernetes CronJob. Vercel cron and AWS EventBridge let you configure concurrency at the platform level.
