    About this tool

    Standard cron has five fields — minute, hour, day of month, month and day of week. Use * for “every”, */n for steps, a-b for ranges and commas for lists. Macros like @daily and @hourly are also understood. When both day-of-month and day-of-week are restricted, cron runs when either matches, and this tool follows that rule.

    FAQ

    Is my data sent to a server?

    No. DevKnife tools run entirely in your browser with JavaScript. Nothing you paste — API keys, tokens, customer data — is transmitted or logged, so it is safe for production data.

    How do I run a cron job every 5 minutes?

    Use */5 * * * *.

    What timezone does cron use?

    The server’s local timezone unless configured (e.g. CRON_TZ). Next runs here are shown in your browser’s timezone.
