Cron Expression Parser
Translate a standard 5-field cron expression into plain English and compute the next scheduled run times. Includes handy presets and validation.
Cron, in plain English
Cron expressions are terse and easy to misread. Paste one and get a clear description like 'At 09:00 AM, Monday through Friday', so you can confirm a schedule does what you intended before deploying it.
See the next runs
Beyond the description, the parser walks the schedule forward and lists the next five run times in your local time zone, each with a relative hint like 'tomorrow' or 'in 3 days' — the fastest way to sanity-check a job.
Standard 5-field syntax
It supports the classic minute, hour, day-of-month, month and day-of-week fields with ranges, lists and step values (like */15). Preset buttons give you common schedules to start from and adapt.
