In honor of World Book Day, April 23, a UK based company has launched a fun tool that tells you the best-selling book for the year you were born.
Wordery says their website is based on the New York Times Bestseller list. All you have to do is type in your age, and it pulls up a timeline showing you the number one book for that year.
From, "Harry Potter and the Prisoner of Azkaban" in 1999, to "It" in 1986.
If you want to see the best seller your birth year, or just any year, click here.
