The Arcana Scheduler was introduced in 1997 as a replacement for the inadequate "AT" scheduler provided with Windows NT. At that time most of the third-party scheduling tools available for Windows NT were large-scale, expensive enterprise scheduling solutions. Our tool was built to fill the void, providing solid basic scheduling at an affordable price.

Ten years later the Arcana Scheduler and its successor, adTempus, are used by thousands of customers in more than 70 countries around the world and in more than 40 Fortune 100 companies.

Now that adTempus is well established and most of our customers have migrated to that newer scheduling platform, the Arcana Scheduler is being discontinued. More information is available here.
