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.
