How to build a cron expression

  1. Pick a preset (every hour, daily, weekly) or build a custom expression.
  2. Adjust the minute, hour, day and month fields.
  3. Read the plain-English description to verify the schedule.
  4. Copy the cron string into your crontab, GitHub Actions or scheduler.

Frequently asked questions

Does this support 5-field or 6-field cron?+

Both. Use 5 fields for classic Unix cron (minute hour day month weekday) or 6 for Quartz-style with seconds.

What does the asterisk mean?+

An asterisk (*) means 'every value in this field'. So 0 * * * * runs at minute 0 of every hour, every day.

Does the schedule respect timezones?+

Cron itself has no timezone — it runs in the server's local time. Configure the timezone in your scheduler (GitHub Actions, AWS, Kubernetes) explicitly.
