What is this tool?

This tool helps you build cron expressions using a visual interface. It provides presets for common schedules, field-by-field editing, a human-readable description, and a preview of the next execution times.

How to Use

  1. Select a preset or edit individual fields (minute, hour, day, month, weekday).
  2. The cron expression is generated automatically.
  3. View the human-readable description and next execution times.
  4. Enter a cron expression manually and click 'Apply' to parse it.

Examples

  • Create a daily backup schedule at midnight (0 0 * * *).
  • Set up a job to run every 5 minutes (*/5 * * * *).
  • Schedule a weekly report on Monday at 9 AM (0 9 * * 1).
