Terms of use

Free to use

The tools on this site are free. You may use the expressions you build here in any scheduler, in any project, commercial or otherwise.

Provided as is

The site is provided without warranty of any kind. Schedules are computed from the expression you enter; a cron daemon may still behave differently depending on its implementation, its timezone and the shell it runs in. Check a schedule on the machine that will run it before you rely on it.

No liability

We are not liable for any loss arising from use of this site, including a job that ran at the wrong time — or did not run at all.

Changes

These terms may change as the site grows; the current version always lives on this page.
