The Date-A-Base Book 2026 front cover. 3,700 historical anniversaries in 2026.

Here are 30 newsworthy and notable historical anniversaries in September 2026 (listed six months in advance so you have time to write about them)

Historical anniversaries are ideal for ‘On This Day in History’ features, articles, biographies and other anniversary tie-ins. They’re popular with newspaper and magazine readers and radio stations, and editors, producers and presenters love them. They’re easy to research too. You can also turn them into movies, documentaries, novels, use them to plan events and exhibitions, and much more. (Find out more at the end of this article.)

We’ve randomly selected an anniversary for each day of the month from The Date-A-Base Book 2026, which lists more than 3,600 anniversaries. The Date-A-Base Book 2027, 2028, 2029 and 2030 are also available.

Each edition is available in British and U.S. versions. Both have the same content, but with different date formats, spelling and grammar.
