Cron Expression Builder

Why this matters

A cron schedule that fires too often can trigger a job storm. One with a subtle midnight, month-end, or daylight-saving boundary bug can silently skip runs, accumulate data gaps, or cascade into larger operational incidents. Most developers write cron expressions by trial and error, deploy, and discover the problem in production logs. A visual builder with live next-run previews catches timing edge cases before they become operational problems: particularly for schedules that cross timezone boundaries, month rollovers, or non-standard intervals that are difficult to reason about in expression syntax alone.
