Abstract: Providing dynamic scheduling services without sharing calendar content, involving retrieving real time availability data and terms applied to calendar time cubes for an invitation to an event with one or more invited users, simultaneously synchronizing between calendars of the invited users in a meeting and event coordinating server to find a combination of common available matching time cubes while considering the terms including arrival time calculations (the common available matching time cubes defined as either “free”, “occupied”, “pending”, ane having a lower level of importance than the event currently created), setting the state of the matched time cubes as occupied at the calendar of each invited user; and rescheduling an event that was previously associated with the sequence of “occupied”, “pending” states with the lower level of importance, the already existing events being automatically subject to changes constantly and immediately.

Abstract: A calendaring method and system providing dynamic scheduling services by synchronizing calendars in a confidential and anonymous manner without the need for sharing calendar content with others. One can divide their calendar into time cubes chronologically, define each time cube according to availability states, allow a user to send data representing an invitation to an event to one or more contacts for approval, and when an invitation of one or more contacts has been approved, opening a secure “private room” in a meeting and event coordinating server adapted for synchronizing between users' calendars in a confidential and anonymous manner. Also a meeting coordinating server adapted for synchronizing between users' calendars via a secure “private room” without using any calendaring content except the availability status of each user, and according to a level of importance, and a dedicated application adapted for running/executing on a user's terminal.
