Depends on my schedule. I can potentially be on PC anytime I'm at home and not at school or working.
Depending on the day, I can be at school anywhere between 7:50am and 12:00pm, plus twenty minutes on either end to account for the commute.
My work schedule is a bit more erratic. On weekdays, they call me into the shop anywhere between 2:00pm and 6:00pm and I usually stay until after we close at 9:00pm. On weekends, I'm completely open and I could be called in at any time and potential stay until closing. XD
So yeah, anytime I'm not at school and not working, I'm more than likely on PC. XD
