Cron Expression Explainer

Paste a cron expression and read it in plain English — with the next five calculated run times. Works with standard 5-field cron, 6-field Quartz (second included), and Jenkins H syntax. Catches common mistakes like day-of-month + day-of-week conflicts.

To build one from scratch use cron expression builder. See the guide on how to write a cron expression. Working in a specific time zone? time zone converter.
