What it's for: Decode any cron expression into plain English and see the next run times. Validate crontab syntax before you deploy it. Instant.
What trips people up: Why did my cron job not run? Most often the field order is wrong (minute, hour, day of month, month, day of week) or the day-of-week and day-of-month fields conflict. The parser shows the interpreted schedule so you can spot it.
