Implementations generally relate to updating events in a social network system. In some implementations a method includes generating one or more event objects having an event information section associated with a first user. The method also includes sending a post from the first user to one or more target users in a social network system, updating the one or more event objects based on the event information section, and causing the one or more updated event objects to be displayed along with the post to the one or more target users in the social network system.
