About the Cron Checker
The cron checker validates a cron expression and shows exactly when it will run next, so you can catch a wrong schedule before it goes live.
How to use it
- 1 Paste a cron expression such as 30 2 * * *.
- 2 Read the plain-English meaning.
- 3 Check the list of upcoming run times.
Frequently asked questions
What does 0 0 * * * mean?
It runs once a day at midnight (00:00) in the server’s time zone.
What happens if I set both day of month and day of week?
In standard cron the job runs when either field matches, not only when both do. This often surprises people.
Are 6-field cron expressions supported?
Standard cron uses 5 fields. Some tools add a seconds field at the start; remove it before checking.
