How this service works
Parse a cron expression into human-readable explanation + next N execution times. Algorithmic — instant.
Output
Returns a plain-language explanation of the cron expression (describing its frequency, days, and times), along with a list of the next N upcoming execution timestamps in the requested timezone, plus a cryptographically hashed audit record for traceability.
Example use cases
Debug a CI/CD pipeline schedule
“I have a cron expression '*/15 8-18 * * 1-5' for my deployment pipeline — can you explain what it does in plain English and show me the next 5 run times in Europe/Berlin timezone?”
Verify a backup job schedule
“Our database backup is set to '0 2 1,15 * *' — can you tell me exactly when it runs and list the next 8 scheduled times in UTC?”
Audit a third-party integration schedule
“I inherited a cron job with the expression '30 6 * * 0' and I have no idea what it does — can you explain it and show me the next 3 times it fires in America/Los_Angeles time?”

Choose this endpoint when you need a quick, auditable, human-readable interpretation of a cron schedule along with concrete next-run timestamps — especially useful in DevOps, automation, or scheduling workflows where non-technical stakeholders need to verify job timing or where audit trails are required.
Side effects
- Invalid cron expression format (missing fields, unsupported syntax) returns a parse error
