Explains cron expressions in plain English, checks them for errors and gotchas, lists next run times in any time zone, and converts between Unix cron, GitHub Actions, Kubernetes, AWS EventBridge, Quartz and Spring dialects.
Validates cron expressions and computes DST-correct next-fire times against real IANA timezone data, flagging schedules that silently skip a spring-forward run or double-fire on fall-back. Also surfaces the POSIX day-of-month/day-of-week OR semantics and other semantic footguns before a job ships.
Enables exploration, explanation, and management of crontab entries, including translating cron expressions into plain English and calculating upcoming execution times.
