Paste a 5-field cron expression below; the schedule and next run times render on the right.
Cron Expression Parser
Paste a standard 5-field cron expression (minute hour day-of-month month day-of-week) and get a plain-English description of the schedule plus the next 5 times it will run.
Parsing happens entirely in your browser - the expression never leaves this device, and nothing is uploaded.
Supports ranges (1-5), lists (1,3,5), step values (*/15), and the wildcard character across all five fields.
An unsupported field, such as a named month or weekday alias, returns an inline explanatory error instead of a silent misparse. No account or signup is required, and nothing you paste here is stored beyond this page session.
Frequently Asked Questions
What does Cron Expression Parser do?
It reads a standard 5-field cron expression (minute hour day-of-month month day-of-week) and shows a plain-English description of the schedule plus the next 5 times it will run - entirely in your browser.
When should I reach for Cron Expression Parser?
Use it to double-check a cron schedule before deploying it, or to quickly translate someone else's crontab line into plain English without installing a scheduler-syntax checker.
Does it support named aliases like @daily or 6-field seconds cron?
No. It supports the standard 5-field syntax with *, comma lists, ranges (N-M), and step values (*/N). Named aliases (JAN, MON, @daily) and 6-field seconds-cron are not parsed.
