About Cron Expression Generator

Writing cron for jobs and CI? Cron Expression Generator on TheToolss builds the minute, hour, day, month, and weekday fields from presets, or takes an expression you paste and explains it in plain English. That second mode is the one that saves real time — reading a schedule string someone else wrote is where most cron mistakes start. Common patterns such as hourly, nightly, and weekday mornings are one click away. Classic 5-field format, matching crontab, GitHub Actions, and most schedulers. Free, private, and no signup.

How to use Cron Expression Generator

  1. Use Build mode with fields or presets.
  2. Or paste a cron expression in Explain mode.
  3. Copy the expression and read the summary.
