Frequently Asked Questions
5 comma-separated fields: minute, hour, day-of-month, month, day-of-week. Leave a field blank for '*' (any) — e.g. '0,9,,,1-5' builds '0 9 * * 1-5' (9 AM every weekday).
If you enter fields, it genuinely builds the cron string from them plus a best-effort plain-English description. If you leave the input empty, it shows a quick-reference list of common patterns instead.
It's a simplified best-effort interpretation covering common cases (specific time, weekday/weekend ranges, day-of-month, month) — it won't perfectly describe every possible complex cron expression, so always double-check the raw cron string too.
No — the expression is built entirely in your browser.
