Time in Spirit World + Moving to New House
How long was Chihiro in the Spirit World? It only seemed like a few days: the night she signed a contract; the day she let in No-Face and bathed the polluted river spirit; the day she saved Haku and returned the gold seal to Zeniba; and then came back from Zeniba's (which was night at the time) to the bathhouse (where it was sunny).
Chihiro's dad said that the package workers had the keys to their new house and could go in to start placing everything there. But since they were in the Spirit World for at least a few days, wouldn't it seem strange to the workers that Chihiro's family hadn't come for days? Also, wouldn't it be weird to themselves, since they supposedly don't remember anything and it only appears to be a couple hours to them, once entering their new home and finding every package there without the workers? How would they find a logical, non-magical, solution to explain this to themselves?
