Cron Expression Parser
Explain a cron expression in plain English and list its next runs.
Supports 5-field cron (minute, hour, day of month, month, day of week) with *, ,, - and */n step syntax, plus the 6-field form with a leading seconds column. Day-of-month and day-of-week are OR-ed together, as standard cron does.
How to use the Cron Expression Parser tool

- Adjust any slider or type an exact number — the answer updates as you go.
- Copy the result and close the tab. Nothing you entered was sent anywhere.
About the Cron Expression Parser tool
Paste a cron expression and get a plain-English reading of every field, plus the next five times it fires in your local timezone. Presets cover the schedules people actually use.
It understands the standard five-field form (minute, hour, day of month, month, day of week) and the six-field form with a leading seconds column, including steps like */15, ranges, and lists. Where both day-of-month and day-of-week are restricted, they are OR-ed together, exactly as standard cron behaves.
