How this service works
Cron expression explainer: human-readable description plus the next run times (UTC) for standard 5-field cron syntax including ranges, lists and steps.
Output
Returns a human-readable English description of the cron expression (e.g. 'Every weekday at 9:00 AM') plus an ordered list of the next N upcoming UTC run timestamps (default 5, max 10), computed from the current time.
Example use cases
Debugging a misconfigured cron job
“I have a cron expression '30 23 * * 0' set up on my server — can you tell me what it does and when the next 5 runs will happen in UTC? I think it might be running at the wrong time.”
Verifying a scheduled report runs at midnight
“We schedule a weekly report with '0 0 * * 0' — can you confirm in plain English when that fires and give me the next 3 UTC run times so I can double-check it matches our expectations?”
Understanding a complex step-interval schedule
“What does '*/10 6-18 * * 1-5' mean and when will it run next? Show me the next 10 occurrences in UTC — I want to make sure it only fires every 10 minutes during business hours on weekdays.”
Technical details
Endpoint
GEThttps://api.aventtech.com/explain/cron?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to explain or audit a standard 5-field cron expression to a human, verify a schedule before deploying, or compute upcoming execution times without running a local cron library. It is ideal for developer tools, chatbots, and scheduling UIs where a quick, authoritative human-readable explanation is needed without any server-side job management.
Side effects
- Invalid or malformed cron expression returns an error explaining the syntax issue
- Count parameter exceeding 10 is clamped or rejected
- Missing 'expr' query parameter returns a 400-style error
- 6-field or non-standard cron syntax (e.g. with seconds) may not be supported and returns an error
