Frequently asked questions
Does the "L" (last day) quick-pick option work in standard cron?
Not in plain Unix/Vixie cron, which is what most Linux crontabs use — "L" is a Quartz-scheduler extension, not part of standard 5-field cron syntax. Check what your specific scheduler supports before relying on it.
Is the plain-English explanation always accurate?
Only for simple values — it correctly describes *, */n (every n units), and common day-of-week shortcuts like weekdays or weekends. A list like "1,3,5" or a range like "9-17" isn't specially parsed, so it just gets pasted into the sentence rather than translated into plain English.
Does this generate a 6-field expression with seconds?
No — it's the standard 5-field format (minute, hour, day of month, month, day of week) used by Unix cron. If your scheduler expects a seconds field, like Quartz or some CI tools, you'll need to add that yourself.
