How this service works
Explain a cron expression (5 fields, names like mon-fri, or @daily) in plain English and list its next run times in any UTC offset. Use to check schedules before deploying jobs.
Output
Returns a plain English explanation of the cron expression (e.g. 'Runs at 9:00 AM every weekday') along with a list of upcoming scheduled run times (up to 20) adjusted to the specified UTC offset.
Example use cases
Verify schedule before deploying job
“I'm about to deploy a cron job with the expression '30 6 1 * *' — can you explain what it does in plain English and show me the next 3 run times in UTC-5 so I can confirm it's right?”
Debug unexpected cron run times
“My cron job with expression '0 0 * * 0' keeps running at the wrong time. Can you explain it and list the next 10 run times at UTC+8 so I can figure out what's happening?”
Understand shorthand cron aliases
“What does the @weekly cron shorthand actually mean, and when will it next run? Show me the next 5 run times at UTC+0.”

Endpoint
GEThttps://bess-x402.onrender.com/v1/dev/cron?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly validate or explain a cron expression in human-readable form before deploying a scheduled job, or when you need to preview upcoming run times in a specific timezone offset. Ideal for DevOps automation agents, CI/CD pipelines, or any workflow that involves cron-based scheduling verification without needing a full scheduling system.
Side effects
- Invalid cron expression syntax returns an error
- Unsupported field count (e.g. 6-field cron with seconds) may not parse correctly
- count out of range (must be 1-20) returns validation error
- timezone_offset_hours outside valid range may return an error or unexpected results
- Service unavailable if Render cold-start delay occurs
