The online tool estimate the age using the Horvath algorithm but using the Hannum's algorithm, among others. It also calculates accelerations applying some calibrations and estimate tissue and gender.

You can also do what Bryant M Schultz said, but on top of what he said, take into account as well the tissue you are studying. Hannum's signature is built from blood samples. Horvarth's signature, on the other hand, was build from a pool of multi-tissue samples.
