How this service works
Validate and explain a cron expression: plain-English meaning, each field expanded, and the next run times in any time zone (DST-aware). Standard 5-field cron, 6-field with seconds, names (MON, JAN) and @daily-style macros. ?expression=*/15 9-17 * * MON-FRI&tz=Europe/London
Output
A JSON object containing: a boolean validity flag, the original expression, a plain-English description of the schedule, an array of field-level breakdowns (minute, hour, day, etc. with parsed values), and an array of upcoming ISO 8601 UTC timestamps for the next N runs.
Example use cases
Debugging a scheduled job
“I have a cron expression '0 9 * * 1-5' — can you tell me what it means in plain English and show me the next 3 times it will fire in US/Eastern time?”
Validating a new cron schedule
“Is '0 */6 * * *' a valid cron expression? If so, when are the next 5 times it'll run, in UTC?”
Understanding a complex interval
“What does the cron expression '@daily' mean and when will it next trigger? Show me 10 upcoming run times in Australia/Sydney timezone.”
Technical details
Endpoint
GEThttps://aayatai.com/cron/explain?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to parse, validate, or explain a cron expression without any external scheduler infrastructure — especially useful for coding agents, DevOps automation, or scheduling tools that need to surface cron meaning to non-technical users. It requires no account or API key and charges only $0.001 USDC per call, making it ideal for lightweight, pay-per-use agent workflows.
Side effects
- Invalid or malformed cron expression returns valid=false with no nextRuns
- Expression shorter than 5 characters rejected by minLength validation
- More than 20 count requested returns validation error
- Unrecognized IANA timezone string may cause error or fall back to UTC
- Missing required 'expression' query parameter returns 400-class error
