How to use the Cron Expression Parser
- Type or paste a cron expression, or pick an example.
- Read the plain-English description.
- Check the next run times.
What does this tool do?
Standard cron uses five fields: minute, hour, day of month, month and day of week. Each field can be a value (5), a list (1,15), a range (1-5), a step (*/10) or a name (MON, JAN).
When both day-of-month and day-of-week are set, classic cron runs when either matches — a rule that surprises many people. The parser follows it.
Why use it?
- Check a schedule before deploying.
- Understand inherited crontabs.
- Catch impossible schedules like February 30.
