How this service works
Next occurrences of a cron expression in any IANA time zone, DST-aware via the runtime's ICU tzdb (times skipped by DST shift forward by the gap; ambiguous times fire once). Dialect (croner): 5-7 fields with optional seconds and year, ranges, steps, lists, JAN-DEC/SUN-SAT names, L, W, #, ? and @daily-style aliases. Each occurrence is returned as local ISO with offset plus UTC. Bad expression → 400 naming the offending field.
Output
A JSON object containing the echoed expression, timezone, start instant, occurrence count, and an array of occurrences each with a local ISO timestamp (with UTC offset) and a UTC ISO timestamp. If fewer occurrences exist than requested, a note field is included.
Example use cases
Example prompt
“What are the next 10 times that the cron expression '0 9 * * 1-5' will fire, starting now, in the America/New_York timezone?”
Technical details
Endpoint
GEThttps://402utils.com/v1/cron-nextWhen to prefer
Use this endpoint when you need to preview, debug, or schedule based on a cron expression and require DST-aware results in a specific IANA timezone. It supports the extended croner dialect (5-7 fields, seconds, year, L/W/# modifiers, named months/days, @aliases), making it more expressive than basic 5-field cron parsers. Prefer it over general-purpose scheduling APIs when you only need occurrence calculation without side effects.
Side effects
- Invalid cron expression → 400 error naming the offending field
- Unsupported or misspelled IANA timezone → 400 error
- count out of range (below 1 or above 50) → 400 error
- Malformed ISO 8601 'from' parameter → 400 error
- Missing required 'expr' query parameter → 400 error
