In Help, e.g. [1], we have date strings that use non-ISO date formats. Unless there is a strong reason to use such format (like when various formats are described/discussed explicitly), it's best to always use ISO 8601 unambiguous date strings, to promote use of international standards helping people understand each other. The task is to find and replace non-ISO dates in Help with their ISO 8601 counterparts - where applicable. Regular expressions like "\d\d?/\d\d?/\d{2,4}" (including double quotes) might be useful when searching them in help repo. [1] https://help.libreoffice.org/6.4/en-US/text/sbasic/shared/03030110.html
