Predictive calendar

1. A method for managing contacts using a calendar application, comprising:

receiving, by a first calendar application on a first electronic device, first travel parameters from a first user through a first user interface of the first calendar application,the first calendar application executed on the first electronic device, and the first travel parameters including a first destination and a first set of travel dates or times;

receiving, by a second calendar application on a second electronic device, second travel parameters from a second user through a second user interface of the second calendar application, the second calendar application executed on the second electronic device, and the second travel parameters including a second destination and a second set of travel dates or times;

determining, by the first calendar application on the first electronic device, at a predetermined time prior to the first set of travel dates or times, whether the first and second users will be present in a particular destination for at least a partially overlapping period of time based on the first and second travel parameters;

notifying the first user of any overlapping dates between the first set of travel dates and the second set of travel dates;

ascertaining, by the first calendar application on the first electronic device, whether the first user has made an indication in the first calendar application indicating the first travel parameters as private;

if the first user has not made the indication, notifying the second user of any overlapping dates between the first set of travel dates and the second set of travel dates; and

if the first user has made the indication, omitting notifying the second user of any overlapping dates between the first set of travel dates and the second set of travel dates.

2. The method of claim 1 , wherein the determining step comprises comparing the first destination with the second destination and the first set of travel dates with the second set of travel dates.

3. The method of claim 1 , wherein said operation of notifying the first user of any overlapping dates between the first set of travel dates and the second set of travel dates further comprises receiving a contact list including one or more contacts from the first user, determining whether the second user is a contact of the first user based on the contact list, and notifying the first user of any overlapping dates between the first set of travel dates and the second set of travel dates if the second user is a contact of the first user.

4. The method of claim 1 , wherein said operation of notifying the first user of any overlapping dates between the first set of travel dates and the second set of travel dates further comprises:

receiving a list including one or more contacts from the first user;

receiving a travel type from the first user;

determining whether the second user is a contact of the first user based on the list;

receiving a contact type from the first user regarding the second user;

determining whether the contact type for the second user matches the first travel type; and

notifying the first user of any overlapping dates between the first set of travel dates and the second set of travel dates if the second user is a contact of the first user, and if the contact type for the second user matches the first travel type.

5. A system for managing a calendar application, comprising:

a first electronic device communicatively coupled to a network, the first electronic device executing a first calendar application configured to receive first travel parameters from a first user including a first destination and a first set of times or dates; and

a second electronic device communicatively coupled to a network, the second electronic device executing a second calendar application configured to receive second travel parameters from a second user including a second destination and a second set of times or dates;

wherein the first calendar application is configured to determine, at a predetermined time prior to the first set of travel dates or times, whether the first and second users will be present in a particular destination for at least a partially overlapping period of time based on the first and second travel parameters;

wherein if the first calendar application determines that the first and second users will be present in the particular destination for the at least the partially overlapping period of time the first calendar application is arranged to notify the first user that the first and second users will be present in the particular destination for the at least the partially overlapping period of time; and

wherein if the first calendar application determines that the first and second users will be present in the particular destination for the at least the partially overlapping period of time the first calendar application is arranged to notify the second user that the first and second users will be present in the particular destination for the at least the partially overlapping period of time unless the first calendar application determines that the first user has indicated that the first travel parameters are private.

6. The system of claim 5 , wherein the first electronic device is further communicatively coupled to a content provider and the first calendar application is configured to obtain destination information from the network or the content provider based on the received first travel parameters.

7. The system of claim 6 , wherein the first calendar application is configured to notify the first user of the obtained destination information at a predetermined time prior to the first set of travel dates or times.

8. The system of claim 5 , wherein the first calendar application is further configured to determine whether the first and second users will be present in a particular destination for at least a partially overlapping period of time by comparing the first destination with the second destination and the first set of travel dates with the second set of travel dates.

9. The system of claim 5 , wherein the network includes a server configured to receive and store the first travel parameters from the first user and the second travel parameters from the second user.
