About this tool
Cron expressions are the standard way to schedule recurring tasks on Unix-like systems. A cron expression consists of five fields -- minute, hour, day of month, month, and day of week -- that together define precisely when a job should run. They are used by crontab, systemd timers, CI/CD pipelines, cloud schedulers, and many application frameworks.
This visual generator lets you build cron expressions by choosing options from dropdowns instead of memorizing the syntax. The generated expression and its next scheduled run times update in real time so you can verify the schedule before deploying. Everything runs in your browser -- no data is sent anywhere.

Frequently Asked Questions
What is a cron expression?
A cron expression is a string of five fields (minute, hour, day, month, weekday) that defines a schedule for recurring tasks. For example, '0 9 * * 1' means 'every Monday at 9:00 AM'.
What do the special characters mean?
* means 'every', / means 'every N intervals' (e.g., */5 = every 5 minutes), - means 'range' (e.g., 1-5 = Monday through Friday), and , means 'list' (e.g., 1,3,5 = Mon, Wed, Fri).
Does it show when the cron job will run next?
Yes. The tool calculates and displays the next 5 scheduled run times based on your cron expression, so you can verify it's correct before deploying.
