Abstract The age of the sun is deduced to be 4.49 + or - 0.04 Gyr. This determination is based on the ages of the oldest meteorites, current models of solar system formation, and the premain-sequence evolution of a 1-solar-mass star from T Tauri phase to the ZAMS. Prior to this it was common to use an age of 4.7 Gyr for the sun. Comparing a solar model evolved to 4.5 Gyr with a model evolved to 4.7 Gyr shows that the 200 Myr difference in their ages has very little effect on the helium abundance and mixing-length parameters of the solar models.
