Events that are described in either structured data (e.g. HTML web page or email) or text in a natural language description can be extracted and entered into one or more calendars on a user's device. In one embodiment, selecting an add event command in a calendar application can cause the calendar application to search, without having received any search input, in a database of extracted events, and events extracted within a predetermined period of time can be suggested as events to add to the calendar. In one embodiment, an extracted event can cause a notification to be displayed to a user. Other embodiments are also described herein.
