About Cron Job Generator
Cron's five-field syntax (minute, hour, day-of-month, month, day-of-week) is compact and powerful, but the field order is easy to mix up if you don't write cron jobs often — accidentally swapping minute and hour is a classic mistake that schedules a job at the wrong time entirely. This tool builds the expression from five clearly labeled fields, so you always know which value goes where.
As you fill in each field, the full cron expression assembles live, along with a plain-language description for common patterns (every minute, daily at a specific time, hourly). Each field shows its valid range directly beneath it, so you don't need to look up cron syntax documentation mid-task.
This is aimed at anyone setting up a scheduled task, GitHub Action, server cron job, or any system that uses standard five-field cron syntax — getting the expression right the first time avoids the classic experience of a job firing at 3am instead of 3pm because of a swapped field.
How it works
- Fill in each field. Minute, hour, day of month, month, day of week.
- Watch the expression build. See the live cron string and a plain-language description.
- Copy the expression. Paste directly into your crontab or scheduler config.
