systemd timers replaced cron on most modern Linux boxes — and they die just as quietly: a timer that stops firing after a reboot, a masked unit, a .service that exits 0 without doing its job. systemctl list-timers only shows the timers systemd still knows about — not the one that silently fell out.

Paste your OnCalendar= lines below. Cronping reads each schedule, derives the interval from the calendar spec itself, and arms a dead-man's-switch per timer. Because the work lives in the paired .service, we hand you the exact ExecStartPost= line to drop in. No account, no signup.

Up to 20 timers per import. We never run anything — we only read the calendar text. A trailing # name becomes the check's name. Specs we can't map (timezones, ~ last-day) are skipped.
