Blazor DateTimeInput provides support for localizing its input field and popup calendarfor different languages and date formats. Each localization is contained within its own file with the language code appended to the name, e.g. globalize.culture.de-DE.js for German. The desired localization file should be loaded along with the datetimeinput.js. The localization is set to the DateTimeInput instance by setting the Blazor DateTimeInput's culture property.
