This study enriches the understanding of relationship work in the context of calendar sharing by examining how people negotiate and enact accountability in their intimate relationships with and around their shared calendars. We conducted 13 semi-structured interviews as part of a qualitative study of Google Calendar users. Our research discovered how participants develop understandings of how close friends and significant others structure their time using shared calendars, as well as how people negotiate and enact accounts within and beyond their intimate relationships. Our findings indicate ways in which Online Calendar Systems (OCS) can be better designed to more effectively support users' needs.
