How long do you consider a sim week?

I feel like The Sims has always been its own timeline, not meant to truly represent reality. I see the Sims Universe as something that exists within its own rules and laws of physics, its own "normalities" (like Occult presence and mythical beings like the Grim Reaper) and its own tendencies. So a week in Sim time is just a Sim week. But a lot can happen in a Sim week because their lives move forward so quickly. And in Sim terms, it's perfectly normal to meet, date, and marry within a Sim week. :)
