This is a list of selected August 20 anniversaries that appears on the "On this day" section of the Main Page. To suggest a new item, in most cases you can be bold and edit this page. Please read the selected anniversaries 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.
Please note that the events listed on the Main Page are chosen based more on how well they are written, not based on how much their subjects are important or significant. Only 5–6 events are posted at a time and thus not everything that is "most important and significant" can be listed.
Also, to maintain some variety of topics on the Main Page as a whole, an event is not posted this year if it is also the subject of the scheduled August 20, 2010 featured article or the August 20, 2010 featured picture.
To report an error when this appears on the Main Page, see Main Page errors. Please remember that this list defers to the supporting articles, so it is best to achieve consensus and make any necessary changes there first.
Admins: after updating please purge the cache of the Main Page so that the updated version appears.August 20: St. Stephen's Day in Hungary
