Frequently asked questions

Which cron format does it use?

Standard 5-field cron: minute, hour, day-of-month, month, day-of-week, including ranges, lists and steps.

Does it show upcoming runs?

Yes — the next five run times, with relative labels.

Is it private?

Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
