Best for

Common situations where this tool fits naturally into the workflow.

Build a cron expression for a daily backup job at 2 AM.
Verify the syntax of a custom cron string to ensure it triggers on the correct days.
Check next execution times to confirm a schedule matches business hours.

Common tasks

Concrete ways this tool is typically used in day-to-day workflows.

Create a job that runs every 15 minutes

Set the Minute field to '*/15' and leave others as '*'. The description will confirm: 'Runs every 15 minutes'.

Schedule weekly Sunday midnight runs

Set the Minute to '0', Hour to '0', Day of Month to '*', Month to '*', and Day of Week to '0' (or Sunday).

Translate a custom expression

Type any valid cron syntax directly into the inputs (e.g. '30 4 1,15 * *') and read the instant English translation.

Caveats and tips

Things to keep in mind before relying on the output in a larger workflow.

Caveats

The generator follows standard 5-field cron specifications. 6-field structures (including seconds or years) are not supported.
Execution intervals are calculated based on the browser's current timezone.

Tips

Double check that the weekday index mapping matches your server's scheduler standard (usually 0 is Sunday).
Use step notations (e.g. */10) to easily represent intervals.
