Why do we call a day 24 hours, if the earth rotates in 23 hours, 56 min? 1. For simplicity – it is about 24 hours 2. We measure a day by the position of the sun, so earth’s revolution around the sun affects the length of day 3. In order to have an integral (even) number of days in each month 4. The earth’s epicycle is about 4 minutes 5. None of the above reasons
