How this service works
Turn a cron expression into plain English, validate it, and compute the exact next execution times. Deterministic — the answer to 'when does this cron actually fire?' without guessing. Use this when an agent needs to explain a cron expression and compute the next runs.
Output
Returns a human-readable English description of the cron expression, a validity indicator, and a list of the next computed execution timestamps based on the provided expression and optional reference date.
Example use cases
Explain a production job schedule
“We have a cron job set to '30 2 1 * *' — can you tell me what that means in plain English and when it will fire next?”
Validate a newly written cron
“I just wrote this cron expression: '*/15 9-17 * * 1-5' — is it valid, and when are the next few times it will actually trigger?”
Debug an unexpected job timing
“Our job is scheduled with '0 0 29 2 *' — can you explain when that actually runs and compute the next execution dates so I know if something is wrong?”
Technical details
Endpoint
GEThttps://agentstoolshub.com/api/v1/dev/cron-describe?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to deterministically explain what a cron schedule does, verify its correctness, or compute exact next-run times — especially useful in CI/CD pipeline review, scheduler auditing, or user-facing automation dashboards where guessing or LLM hallucination is unacceptable.
Side effects
- Invalid or malformed cron expression returns a validation error
- Missing required 'expr' query parameter returns a 400 bad request
- Cron expressions with impossible schedules (e.g. Feb 30) may return no upcoming execution times or an error
- Expression with wrong number of fields (not 5) will fail validation
