Cron Expression
Runs every minute.
How does it work?
Build a standard 5-field cron expression without memorizing the syntax. Pick values for minute, hour, day of month, month, and day of week from the dropdowns (or leave one as * for "every"). The expression updates live along with a plain-English description.
Example
Setting hour to 9 and minute to 0 (with everything else *) produces 0 9 * * * — a job that runs once a day at 9:00 AM.
Common Use Cases
- Writing scheduled jobs in CI/CD pipelines, Linux cron, and server maintenance scripts.
- Generating backup, report, or cleanup schedules without looking up the syntax.
- Learning how cron's five fields map to real schedules.
FAQs
What does the * mean?
An asterisk in a field means "every" — so * * * * * runs every minute of every day.
Does day of week start at 0 or 1?
Standard cron convention is 0 = Sunday through 6 = Saturday, which is what this generator uses.
