Frequently Asked Questions
What is a cron expression?
A cron expression is a string of five fields (minute, hour, day of month, month, day of week) that defines a schedule for recurring tasks. It's used in Unix/Linux cron jobs, CI/CD pipelines, cloud schedulers, and task automation tools.
What does each field mean?
The five fields are: Minute (0-59), Hour (0-23), Day of Month (1-31), Month (1-12), Day of Week (0-6, where 0 is Sunday). Use * for 'every', */N for 'every N', and comma-separated values or ranges (e.g., 1-5).
How do I schedule a job every 5 minutes?
Use the expression '*/5 * * * *'. The */5 in the minute field means 'every 5 minutes', while the asterisks in other fields mean 'every hour, every day, every month, every day of the week'.
