You can date rocks less than about 600 million years old using fossils (provided they have fossils in them). This gives you a relative age based on the evolution of species.
To obtain an absolute age one uses radio isotope dating, a technique based on the half life of the decay of radioactive elements in the rocks.

∙ 11y ago~ One dating method is to compare objects found in similar layers of rock or soil.
~ Archaeologists may also compare an object with a similar fossil of artifact whose age is already known.
~ Radioactive dating is another method for determining the age of very old objects.
