- "When they had sung many songs, and talked of many things they had done together, they toasted Bilbo's birthday, and they drank his health and Frodo's together according to Frodo's custom."
- ― The Fellowship of the Ring, Three is Company
The Birthday Toast was an event held each year at a small gathering in honour of both Bilbo Baggins' and Frodo Baggins' birthdays, held each year on the 22nd of September at Bag End (both hobbits shared the same birthday).
This custom began after Bilbo left Bag End after the celebration of his 111th birthday.
 Tolkien Society tradition
The Tolkien Society has upheld this tradition through a Birthday Toast in honour of the creator of Bilbo and Frodo - J.R.R. Tolkien and is held on the author's birthday, 3rd January, each year. The 'toast' itself is: "The Professor".
