The Arcana Scheduler is a scheduling service for Windows NT/2000/XP¹, used to automatically run programs at specified times. The Arcana Scheduler is not just another graphical front-end to the at scheduler included with Windows. Instead, it was written as a complete replacement, providing flexibility not available in the at command's scheduling engine or in the newer Windows Task Scheduler.

Use the Arcana Scheduler to schedule programs, scripts, batch files, spreadsheet updates, system shutdowns and restarts, backups , or anything else you need done at a specific time.
