Cron expression editor
Minute, hour, day of month, month, day of week. Next runs are computed in this device's timezone — the same rule crontab itself uses on the machine it runs on.

When both day-of-month and weekday are restricted, cron fires when either matches — an OR, not an AND. Nobody guesses that; the next-runs list above honours it.
