In summer, day hours are longer than night hours. There is no smaller division like a minute : 10 days = 1 week, weeks are organized according to the observation of the decanal stars. That"s why they had 3 calendars: solar, lunar, astronomical: attempts to regulate/adjust these. Days that exist outside the usual organization of months, etc. Days that aren"t part of a month that are thrown in. Days with this kind of power could be lucky or bad luck. Many festivals on them, celebrated as part of the new.
