I'll bite. If you're in marketing (and this conference, like most others, is primarily about marketing) then no, there are more than the two binary states. There's the official conference presentations - the "ON" - but the "OFF" is harder to define. There's the afterhours. There's the email and social media stuff about this or that product launch/release that goes on as people are thinking about the conference, and follow-ups to the marks who swiped their badges or whose names were purchased from the attendee lists. And if you were one of the working stiffs expecting to get paid to set up, tear down, serve food, pick up trash, etc. then your "ON" also has, er had, extra hours.
