Do you mean 12 as in midnight? Sorry, maybe I'm reading incorrectly (I'm tired!) but I guess I'm not totally comprehending your times.
But I can say that my 2 Syrians have weird schedules. They both often sleep until late into the night (like 1 or 2am) and then they're awake all morning and into the early afternoon. I suffer from insomnia so I think my whacky sleeping habits have rubbed off on them a bit.
