Abstract
In this paper, we analyze the agegraphic dark energy from the entropy of the anti-de Sitter black hole using the age of the universe as the IR cutoff. This model realizes the whole evolution of the universe, including the late-time accelerated expansion, and is consistent with observational Hubble data. Although it asymptotically approaches the standard $\Lambda$CDM model in the future, statefinder analysis shows that late-time deviations allow the two models to be distinguished.
