Cron Expression Generator

Build a cron schedule from presets and weekday taps, or paste an expression to decode it. You get plain English, the next five runs, and a calendar of fire days — nothing is uploaded or scheduled.

How to use Cron Expression Generator

  1. 1. Pick Build or Decode. Build from common rhythms, or paste a 5- or 6-field expression.
  2. 2. Tune the fields. Minute, hour, day, month, and weekday controls update the expression live.
  3. 3. Preview and copy. Read the English sentence, check the next runs, then copy the expression or OnCalendar line.

About this tool

People searching “cron expression generator” want a schedule they can paste into crontab — not a lecture on fields. This alias lands on the visualizer with generator intent in the title.

Generator vs explainer

Generators start from human intent (weekdays at 9:00). Explainers start from an expression you already have. This suite does both on one page so you can round-trip without opening two tabs.

Why preview next runs

A sentence can still hide DOM vs DOW surprises. Seeing the next five fire times and which days light up on the calendar catches mistakes before they hit production.
