Here are 30 newsworthy and notable historical anniversaries in September 2025 (listed six months in advance so you have time to write about them)
Historical anniversaries are great 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 2025, which lists more than 3,600 anniversaries. The Date-A-Base Book 2026, 2027, 2028 and 2029 are also available. The 2030 edition will be published in April 2025.
Each edition is available in British and U.S. versions. Both have the same content, but with different date formats and spellings. If you click on the links above, you should be directed to the correct version, based on your location. We’ve taken the anniversaries below from the British version.
