Ongoing maintenance of date formats may one day be carried out by bots on articles already tagged with templates ({{use dmy dates}} or {{use mdy dates}}) which help to identify the correct format. Potentially ambiguous dates, using slashes or full stops (6/7/1961, 12/07/1986, 6.7.1961, 12.07.1986) are re-appearing on some thousands of pages ...
