Rotational Players - How long does it take you to rotate through every sim?

I almost chose 'do my own thing', but really either option fits. I have 4 main households I focus on and another 8 to 10 that I rotate through on occasion. My rotation save is also a story I share on here, so the story guides me on when to move and where. Most of my sessions cover two or three sim days, and I may stay with one household the whole time or I may visit 3 or 4.
