What is a daily cron job?
A daily cron job is a scheduled task that runs once every day at a specified time. The basic pattern is 0 H * * * where H is the hour (0-23). For example, 0 3 * * * runs at 3:00 AM daily. You can also specify a minute for more precision, like 30 2 * * * for 2:30 AM every day.
Common use cases
Daily cron jobs are used for database backups at off-peak hours, sending daily digest emails, generating overnight reports, cleaning temporary files, rotating logs, refreshing caches, and syncing data between systems. Scheduling during low-traffic periods (typically 2-5 AM local time) minimizes impact on production workloads.
Frequently Asked Questions
What time zone does a cron job use?
Standard cron uses the system's local time zone. In Kubernetes CronJobs, you can set the time zone with the timeZone field (since v1.27). Cloud services like AWS EventBridge let you specify a time zone per rule.
Can I run a daily cron job at multiple times?
Yes. Use a comma-separated list in the hour field. For example, 0 8,20 * * * runs at 8 AM and 8 PM daily. You can list as many hours as needed.
