How this service works
Explain a cron expression in plain English and list its next run times in a time zone (5 or 6 fields, with ranges, steps, L, W and #).
Output
Returns a plain-English description of the cron expression's schedule and a list of upcoming run timestamps (up to 50) in the requested IANA time zone, covering 5- and 6-field expressions with ranges, steps, L, W, and # syntax.
Example use cases
Explaining a job schedule to a stakeholder
“My cron expression is '30 8 1 * *' — can you explain it in plain English and show me the next 5 times it will run in Europe/London?”
Debugging a complex cron expression
“I have this cron expression '0 0 * * 5L' and I'm not sure what it does or when it fires — can you break it down and list the next 10 run times in UTC?”
Verifying a deployment schedule
“We schedule deployments with '0 2 * * 6#2' — can you explain when exactly that runs and show me the next 5 occurrences in America/Chicago?”
Technical details
Endpoint
GEThttps://qcb7fnxsbd7fbhj4.68r.lambda-web.us-east-1.on.aws/v1/cron?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to interpret or debug a cron expression in natural language, or compute the precise upcoming run times of a scheduled job — especially when dealing with advanced cron syntax like L (last), W (weekday), or # (nth weekday) that many simple parsers do not support. It supports both 5-field (standard Unix) and 6-field (with seconds) expressions.
Side effects
- Invalid cron expression returns an error describing the parse failure
- Unsupported IANA time zone name results in an error
- Count outside 1-50 range is rejected with a validation error
- Missing required 'expr' query parameter returns a bad request error
