Cron expression helper

Paste a standard five-field cron string. We split it by field so you can match each part to the reference in the article below.

Five fields, space-separated: minute hour day-of-month month day-of-week.

Field Value
Minute 0
Hour 12
Day of month *
Month *
Day of week 1-5

Raw string: 0 12 * * 1-5

Semantics depend on your scheduler (e.g. Sunday as 0 or 7). This helper only splits fields — use your engine’s docs for validation and next-run times.

Encode strings for data URLs or decode snippets from logs. Works fully in the browser for quick checks.
