Bilbo was born to Bungo Baggins and Belladonna Took on September 22, T.A. 2890, or S.R. 1290. The Bagginses of Bag End were one of the oldest, wealthiest, and most respectable hobbit families in Hobbiton until the year 2941 (SR 1341), when Bilbo inexplicably disappeared on his adventure and was thought dead.Though at first an unlikely hero, he accompanied Thorin Oakensheild and his company of Dwarves to retake the Lonely Mountain from the dragon Smaug. It was on this journey that Bilbo would acquire the one ring.

When Frodo and the other Hobbits return to Rivendell on their journey home to the Shire, Bilbo is still alive but now visibly aged, the years having caught up with him after he surrendered the Ring. Finally Bilbo accompanies Gandalf, Elrond, Galadriel, and Frodo to the Grey Havens, there to take ship for Tol Eressea across the sea, on September 29, T.A. 3021. He had already celebrated his 131st birthday by this time, surpassing the Old Took by one year and becoming the oldest living Hobbit ever in Middle-earth.
