Abstract: This disclosure concerns visualizing multiple time zones in a calendar. A processor receives trip data that identifies a trip day, a first time zone of a departure location and a second time zone of an arrival location. The processor determines time gained or time lost due to travelling from the first time zone into the second time zone and causes the display of a time range and a graphical element. The time range represents the trip day with time values extending to the end of the trip day. The end of the trip day is relative to the first time zone. The graphical element extends from the day change and has an extension based on the difference between first and second time zones, such that the graphical element indicates the determined time gained or time lost due to travelling from the first time zone into the second time zone.

Abstract: This disclosure relates to managing a time period in a calendar application between multiple events. A processor receives from a requesting device a request for time management data. The processor then determines for each of multiple activities having respective activity locations an available length of time for performing that activity within the time period. This determination is based on a travel time for travelling between the event locations and the activity location of that activity. The processor sends the time management data including the available length of time for each of the multiple activities to the requesting device. The requesting device has the available length of time for each activity available and can provide this information to a user of the device. The user can think about whether the available length of time is sufficient for the respective activity and therefore supports a better and more efficient planning outcome.
