This tool needs JavaScript. Everything it does runs in your browser and nothing is sent to a server, so with JavaScript switched off it cannot calculate, generate or draw anything.

Cron Builder and Explainer

Write a schedule in plain English or German, build it field by field, or paste an expression and find out what it actually does. Everything runs in your browser.

Times are calculated in your own timezone, the same way Vixie cron and cronie schedule jobs. When both day of month and day of week are restricted, cron runs the job when either matches.
