How do we measure the earth's age

The age of Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 10 years ± 1%). This age may represent the age of Earth's accretion, or core formation, or of the material from which Earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial material and lunar samples.
