Parse cron expression
How it works
Parsing and encoding run entirely in JavaScript here—no server sees your pasted content unless a tool explicitly says it fetches remote data.
Examples
- `0 9 * * 1-5` -> 9:00 every weekday.
- `*/15 * * * *` -> every 15 minutes.
- `0 0 1 * *` -> midnight on the first day of each month.
Use this tool for
- Formatting or minifying snippets before pasting into a repo or ticket.
- Checking encodings (Base64, hex, URL) without third-party paste services.
- One-off developer checks during debugging.
Common questions
Does Cron Expression Parser cover every edge case for Cron Expression Parser?
Confirm the field units (px, degrees, charset) match what you intend; mixed bases are the usual surprise on this kind of tool.
Is anything I type sent to NexUtility servers?
Different rounding or parsing rules can shift edge-case output—sanity-check with a tiny hand example when precision matters.
