1. A processor-implemented event calendaring method to transform event data to eventual event calendars, comprising: receiving, by a processor from a source, calendar event data; receiving, by the processor from a user, user calendar event interest data and user specified preferences; storing the calendar event data in a calendar event database, wherein storing the calendar event data includes structuring the calendar event data according to event type, event frequency, and event audience; querying the calendar event database with the user calendar event interest data; scoring, by the processor, the query results based on historical statistical analysis, the user specified preferences, and a relationship to openings in a calendar of the user; providing calendar event recommendations based on populated calendars of other users; receiving selections, from the user, associated with the scored query results; generating, by the processor, user calendar entries from the received selections; and providing, by the processor, the generated user calendar entries to the user.
