Cron expression generator

Pick minute, hour, day, month, and weekday values (including stars, lists, and steps). The page writes a classic five-field cron string used by crontab and many CI schedulers.

This is not Quartz (seconds/year) and not systemd OnCalendar. AWS EventBridge and Kubernetes cron jobs have their own dialects — verify in the target docs.

How to Use

  1. Choose how often the job should run (every N minutes, daily at 03:00, weekdays, etc.).
  2. Copy the five-field expression.
  3. Paste it into crontab or your platform’s cron field.
  4. Confirm timezone. Crontab uses the machine TZ unless you set one.

Key Features

  • Visual fields plus the raw expression
  • Human-readable summary
  • Local only — we do not run your job
  • Useful before you SSH into production

Frequently Asked Questions

Does this include a seconds field?

No. It is UNIX-style five fields. Jenkins/Quartz seconds are a different format.

Will FlashKit execute the cron?

No. We only generate the string.
