Paste a standard 5-field cron expression and get a plain-English explanation plus the next 5 upcoming run times, computed entirely in your browser.
A: Standard 5-field cron syntax: minute, hour, day-of-month, month, day-of-week. Named months (JAN-DEC) and weekdays (SUN-SAT) are supported alongside numbers.
A: Cron treats this as OR, not AND — the job runs if either field matches, per standard cron semantics. This tool follows the same rule when computing the next run times.
A: Yes, calculations use your browser’s local time zone. If your scheduler runs in UTC or another zone, account for the offset.
A: Not currently — this tool parses standard 5-field cron (minute hour day-of-month month day-of-week), the format used by crontab and most schedulers.
