It's more complicated than that, Skinny.
Yesterday started off as a normal Friday (usual news programmes on 5Live). At some point after dinnertime it morphed into a Saturday (some football match on Radio Devon). Early evening, it changed back into a Friday (Kicking Off on 5Live), then later it became a Sunday (watched a film on telly).
Apparently it's Saturday today (Danny Baker and Fighting Talk on 5Live) but I'm on my guard in case it turns into another day. Wednesday, perhaps.
