Is this tool sufficient for critical production tasks?

This tool is an auxiliary reference tool; it does not replace professional systems engineering consulting. Before affecting critical production cron configurations, it is recommended that you verify them with an expert.

Is the time zone difference reflected in the calculations?

Yes, by selecting UTC or your local time from the time zone selection field, you can display the trigger times correctly.

Yes, it is completely free. You do not need to create an account or make a payment.

Why does it say 'every Monday at 02:00' but the trigger time comes out different?

It may be caused by the time zone difference. Make sure your time zone selection is set correctly; if the server time is UTC, you need to write your cron expression accordingly.

Is data sent to the server?

No. All analysis takes place in your browser; the cron expressions you enter are not transmitted to any server.
