How many hours exactly is a day?
Modern timekeeping defines a day as the sum of 24 hours —but that is not entirely correct. The Earth’s rotation is not constant, so in terms of solar time, most days are a little longer or shorter than that. The Moon is—very gradually—slowing the Earth’s rotation because of friction produced by tides.
