Anyway the Egyptians used sundials during the day and water clocks at night [water clocks are like hour glasses but with water instead of sand] to keep track of time, dividing both day and night into 12 parts each. So a full day cycle is 12 hours of day and 12 hours of night, thus 24 hours [total].
