Absolute hours are hours above the 24 hour mark. Its absolute not because of quantity but due to the finite amount it can be divided into. We do not count passed 24 hours in a day; not because of earths rotation around the sun which gives us "day" and "night" but because that would require a single time keeper through the history of time, ultimately binding the world together by the same hour count from when the clock first begun. Do not confuse that for what we call "years", I'm talking about absolute hours.
