Cron Parser
TimeParse and explain cron expressions
Paste a cron expression like `0 9 * * 1-5` and get a plain-English explanation of exactly when it fires, or build the schedule field by field (minute, hour, day, month, weekday) and watch the expression assemble itself as you go. It supports standard 5-field cron, the format crontab, GitHub Actions, and most schedulers actually use. Cron expressions are timezone-agnostic by nature, so the explanation describes the schedule in relative terms rather than pinning it to a specific zone, since that's determined by wherever your scheduler actually runs. This tool explains what a schedule means in words; it doesn't compute actual future timestamps. For that, the companion Cron Next Runs tool lists the next N real run times rather than just describing the pattern.
How to use Cron Parser
- 1.Paste a cron expression like `0 9 * * 1-5` to get a plain-English explanation of exactly when it runs.
- 2.Build a schedule field by field (minute, hour, day, month, weekday) and see the resulting expression update live.
- 3.Use the Cron Next Runs tool alongside this one to preview the actual next N run timestamps, not just a description.
