Scheduler Dashboard (shipped as Tickwork) is a complete front end for managing recurring jobs. A hand-written cron engine understands five-field expressions, ranges, steps, lists, month and weekday names and @daily style shortcuts, reports mistakes with the exact character position, and turns every valid expression into a plain-English sentence and a time-zone aware list of upcoming runs shown in local time or UTC. Around it sits a job manager (create, edit, pause, duplicate, delete with undo, tags, search, filters), a visual cron builder, a mock runner with retries, streamed logs, a live scheduler clock and a 1x to 3600x speed multiplier, a run history timeline, stats cards with inline SVG charts, and JSON export and import.

Plain HTML, CSS and vanilla JavaScript with localStorage, light and dark themes and accessible markup. The runner never executes commands; the one file that would talk to a real scheduler is isolated so you can connect your own API.
