Frequently Asked Questions

What does each field in 0 9 * * * mean?

A cron expression has five fields separated by spaces: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-7, where 0 and 7 are Sunday). The */n syntax means "every nth interval." In 0 9 * * *, the fields are: 0 — at the top of the hour; 9 — at 9 AM (server time); * — every day of the month.

How do I verify that 0 9 * * * is correct?

Use the EpochPilot Cron Expression Builder to paste your expression and see the next run times visually. You can also use the crontab -l command to list your current crontab entries, or test with a simple echo command: 0 9 * * * echo "test" >> /tmp/cron-test.log.

What timezone does cron use?

By default, cron uses the system timezone configured on your server. On most cloud servers this is UTC. You can check your system timezone with timedatectl on Linux or date +%Z. Some cron implementations (like Kubernetes CronJobs) let you specify a timezone explicitly. Always verify your server's timezone to ensure jobs run at the expected times.

Try the Cron Expression Builder to create and test cron schedules.
