Frequently Asked Questions
What is a cron expression?
A cron expression is a string of 5 fields (minute, hour, day of month, month, day of week) that defines a recurring schedule. It's used in Unix/Linux cron jobs, CI/CD pipelines, and scheduled tasks.
What does * mean in a cron expression?
The asterisk (*) means 'every' — it matches all possible values for that field. For example, * in the minute field means 'every minute'.
What does */5 mean?
The */N syntax means 'every N'. So */5 in the minute field means 'every 5 minutes' (0, 5, 10, 15, etc.).
Is this a crontab guru alternative?
Yes. This tool provides the same functionality as crontab.guru — parsing cron expressions into human-readable descriptions with next run times — but runs entirely in your browser with a cleaner interface.
