Calendar user interface search and interactivity features

Systems and devices for presenting coordinated event search results in a user interface for a calendar are disclosed. In an example, operations include: generating a calendar surface user interface, to display at least one event in a calendar view; receiving a search query for a search of the calendar; generating a search result user interface, to display events from a result of the search query; and updating the calendar surface based on the search result, with the display of the events in the calendar surface being updated based on a match with the search query. As various examples, based on the search results or the search query: the search result portion may indicate that a corresponding event is displayed within the calendar surface portion; graphical emphasis effects may be applied to search results or events; or graphical de-emphasis effects may be applied to search results or events.
