Cron parser
Explain a cron expression and show the next run times (local or UTC). Copy results or share a link.

Supports basic 5-field cron: minute hour day-of-month month day-of-week. Use *, lists, ranges, and steps (e.g. */5, 1-10/2).

Tip: “Share link” stores your expression and options in the URL hash so you can reopen the same preview.
