Computer scientist William Tunstall-Pedoe, developer of the search engine True Knowledge, has determined that April 11, 1954 was the most boring day of the 20th Century. His conclusion is based on an estimate of notable births, deaths, and events:
Every day something of significance happens, a person is born who is destined for fame, there is an event in the arts or sports, history is created. With 300 million of these facts fed into the "brain" of True Knowledge, Tunstall-Pedoe's Cambridge company, the computer was asked: "What was the most boring day in the 20th century?"[...]
Nearly five million people are using True Knowledge every month, asking their own questions and contributing factoids and context to improve the quality of search.
Many of these facts include dates.
