A system and method are provided for scheduling, calendaring, notifying, and providing automated real-time updating of scheduled appointment times on a central master schedule. The system and method dynamically optimize a number of appointments being scheduled within a range of time using a distributed computing system suitable for providing a self-service model for patient driven scheduling of appointments. Specifically, the system optimizes scheduled appointment times in response to a break in the schedule or a manual update of a specific scheduled appointment to maximize the number of appointments capable of being scheduled within a defined work day for the service provider. A plurality of edge-connected devices act as the initiators of scheduling changes, while creating an edge-connected schema for handling elastic scheduling tasks that are reflected on the centrally placed master calendar residing on a passive peer-validated data store and/or database.
