Don't worry, it's the same day ^^ Just weird stuff going on with the mage, drugs, booze, lack of sleep and Magic don't mix well.
Just after waking up, Simone went to the farm with Nyx, then there was the breakfast at the Gates, and after that, some went to the security firm, Simone and Maxwell went to her van to sleep (and stuff), Nyx stayed at the Gates. So same day, and probably not even that much time difference at all.
