Cron Expression Generator

Build a five-field cron expression from presets or by hand, then read it back in plain English with the next run times.

Common presets

Minute (0-59)

Hour (0-23)

Day of month (1-31)

Month (1-12)

Day of week (0-6, Sun=0)

Expression, description and next runs

How it works

Standard five-field syntax is used: minute, hour, day of month, month, day of week — with *, lists (1,3,5), ranges (1-5) and steps (*/15).
The description is generated in plain English, and the next five matching times are calculated from your local clock.
Choosing a preset fills every field, so you can tweak just the part you need.
