The age in years of a rock or other object is known as Absolute Age.
Absolute geologic age is determined through radiometric dating, and is the most precise method for determining the age of a rock or fossil within a small range. Relative geologic age is determined by the index fossils that may be contained within the rock that indicate a much broader range of possible ages based on the time the organism existed on Earth.
What you are referring to is the relative age.

age of a rock unit in number of years before present (numerical age).
Relative age does not assign a number to an age, but is only used to say, for example, whether rock A is older than rock B. Absolute age actually assigns a number, for example "this shale is about 300 million years old."
In terms of geology, Relative Age is the age of an object in relation to the ages of other objects. Layers of rock, called strata, show the order of events that took place in the past and Absolute Age is the numerical age of an object or event.
