Cron Expression Generator — frequently asked questions
What is a cron expression?
A cron expression is a string of five (or six) fields separated by spaces that defines a recurring automated job schedule in Unix-like operating systems and task runners.
What do the five standard cron fields represent?
From left to right, the standard 5 fields represent: Minute (0–59), Hour (0–23), Day of Month (1–31), Month (1–12 or JAN–DEC), and Day of Week (0–6 or SUN–SAT).
Which common schedule presets are provided?
The generator provides presets for Every Minute, Hourly, Daily at Midnight, Weekly on Sunday, Monthly on the 1st, and Every Weekday (Monday through Friday).
Can I see upcoming scheduled run times?
Yes. The tool parses the cron syntax and computes the next five upcoming execution timestamps so you can verify the schedule matches your requirements.
Is my schedule private?
Yes. All expression parsing, natural language translation, and schedule calculations run locally on your machine with zero server involvement.
