FAQ

Common questions about cron expressions.

What is a cron expression?

A five-field string controlling when a job runs: minute, hour, day-of-month, month and day-of-week.

What do the five fields mean?

NaN

Are presets available?

Yes. Six common schedules — every minute, hourly, daily, weekly, monthly and yearly — set the fields for you.

Is the expression validated?

Every change re-computes the expression and its description live, so you can confirm the schedule at a glance.

Which timezone is used?

Cron itself is timezone-dependent. This tool only builds the expression — the scheduler’s timezone applies when the job runs.

Is it free and browser-based?

Yes. Everything runs locally in your browser with no account and no uploads.
