使用说明

Translate a Cron expression into a human-readable schedule and preview upcoming runs.

Standard format

Parsed as the standard 5 fields: minute hour day month weekday.

Schedule preview

Lists the next few run times so you can verify they match expectations.

Note

Systems differ in supporting a 6th (seconds) field and in how the day-of-month and day-of-week fields interact; this tool follows the common 5-field standard.
