Cron API

A fast, fully-local cron-expression toolkit (UTC): validate 5-field cron expressions with ranges, lists, steps, month and weekday names and the common @aliases (@yearly, @monthly, @weekly, @daily, @hourly); compute the next N run times for a schedule from now or any start date; and describe a schedule in plain English. Every endpoint accepts input via the query string or the request body. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for schedulers and job runners, devops and CI tooling, and dashboards that show the next run time of a task.
