How do I reset my sleeping patterns?

This sounds like a riddle or brain teaser, however it is not lol

Every day I fall asleep at 4 or 5 a.m.

On Monday, Wednesday, and Friday I have to get up at 9 a.m. (4 or 5 hours of sleep).

On Tue. Thur. I sleep in until 1 p.m. (8 or 9 hours of sleep).

I’m dead tired on the days I have to get up at 9 a.m., but I can’t fall asleep until 4 a.m. because I slept in until 1 p.m. and I can’t wake up earlier than 1 p.m. because my body is so tired from only having 4 hours of sleep.

Any suggestions on how to get into a sleeping pattern of 12 a.m until 7 a.m.?
