This is a list of selected September 13 anniversaries that appears on the "On this day" section of the Main Page. To suggest a new item, be bold and edit this page. Please read the guidelines before making your edit. However, if your addition may be controversial, or on a day that is or soon will be on the Main Page, please post your suggestion on the talk page instead.

Only 5–6 events are posted at a time. To maintain some variety of topics on the Main Page as a whole, an event is not posted this year if it happens to coincide with the current week's RITpedia:Featured article or the RITpedia:Featured picture.

Admins: after updating please purge the cache of the Main Page so that the updated version appears.
