A digital calendar sharing control and visibility system and method for providing a user with control and visibility of digital calendar sharing. The system and method enhance and improve the sharing capabilities of current digital calendar applications. The system and method include a time-based (or expiration) sharing feature that gives a user control over the expiration date of the calendar sharing. The user can expire the sharing after a certain duration or date. The user also can specify a date range or a time range that a person can view in the user's digital calendar. A sharing audits and history feature allows a user to view who has looked at their calendar and what calendar information has been viewed. A private notes section allows a user to enter information that will not be seen by another person, even if that person has sharing permission to view the user's calendar.
