I heard that the Earth rotation is slowing down, but I also heard the Earth's length of day is increasing.

Does the two theories go together or conflict with each other?

Yeah, question about Earth is totally too localized – user11153 Jan 7 '14 at 10:59

If you slow down, it will take you longer to type a sentence, won't it?

When the Earth slows down (i.e. the speed of rotation is decreasing), it will take longer to complete a rotation, so the day is longer (i.e. the length is increasing).
