Frequently Asked Questions
What is a cron expression?
Cron expressions define schedules for recurring tasks using 5-6 fields: minute, hour, day, month, day of week (and optionally seconds).
What does the asterisk mean?
An asterisk (*) means "every" value for that field. E.g., * in hour means every hour.
How do I schedule daily tasks?
Use "0 0 * * *" for midnight daily, or "0 9 * * *" for 9 AM daily.
What is the difference between / and -?
/ means step (*/5 = every 5), - means range (1-5 = 1 through 5).
