Frequently asked questions
- Is the cron explainer free?
- Yes — free with no signup.
- Which cron flavor?
- Standard 5-field POSIX cron (minute, hour, day, month, weekday). 6-field 'seconds-first' cron used by Quartz isn't supported.
- Are my expressions uploaded?
- No — every parse runs in your browser.
- What about ranges and step values?
- Ranges (1-5), lists (1,3,5) and steps (*/15) are supported — they round-trip through cron-parser correctly.
- Why are the next runs in UTC?
- Cron schedules don't carry a time zone. Showing them in UTC makes comparisons unambiguous; convert to local with our Timezone Converter.
