Result

This page opens the builder preloaded with */5 * * * * — the classic 'every five minutes' schedule, 288 runs per day. The */5 in the minute field means 'start at minute 0 and repeat every 5 minutes': 0, 5, 10, … 55, while the four asterisks leave hour, day, month and weekday unrestricted.

Five-minute intervals are the workhorse of operations: health checks and uptime probes, queue and mailbox polling, cache refreshes, metric collection and small sync jobs. It is frequent enough to feel near-real-time, yet leaves room for a job that occasionally takes a minute or two — though if your task can ever run longer than the interval, add a lock (flock or a PID file) so runs do not pile up.

One subtlety worth knowing: step values count from the range start, not from the moment you install the job — */5 always fires at minutes 0, 5, 10…, never at 2, 7, 12. Need a different rhythm? Change the N in the minute field to get */10 or */15, or switch the field to specific values like 2,7,12 — the expression, the explanation and the next-run list update as you type.

Accepted Formats & Rules

  • Per-field builders for minute, hour, day of month, month and day of week: every value, every N, or specific lists and ranges (0,30 or 9-17).
  • Live human-readable explanation of the schedule with localized month and weekday names.
  • Next 5 run times computed with real calendar math, including the POSIX day-of-month OR day-of-week rule.

Key Benefits

✓ No syntax to memorize: choose 'every', 'every N' or specific values per field and the five-part cron expression assembles itself.
✓ Instant feedback — a plain-language description and the next 5 computed run times show whether the schedule really does what you meant.
✓ Runs entirely in your browser and works offline, so server schedules and job names never leave your machine.

Use Cases

  • • Build the cron expression for a nightly backup job without memorizing the five-field syntax.
  • • Verify when a schedule will actually fire by reviewing the next five computed run times before deploying it.
  • • Turn 'every weekday during business hours' into a valid crontab line for a monitoring script.
