MonatTagJahr

MonatTagJahr is a term used in German-language discussions to describe a date format in which the order of date components is Month, Day, then Year. It is a descriptive label for the US-style date sequence and is not a formal international standard. In written form, it corresponds to numeric representations such as MM/DD/YYYY or MM-DD-YYYY, where the first component is the month, the second is the day, and the third is the year.

In practice, MonatTagJahr appears in contexts such as software localization, form design, and data interchange when the user interface or data schema follows the month-day-year order. The term is often contrasted with other common orders, such as TagMonatJahr (DD/MM/YYYY) used in many parts of the world, and with JahrMonatTag (YYYY-MM-DD), as in ISO 8601. The choice of format affects parsing, display, and user expectations, and many systems rely on locale settings or explicit format specifications to avoid ambiguity.

Ambiguity can arise with dates like 04/11/2024, which may represent April 11 in MonatTagJahr contexts or November 4 in other conventions. To reduce confusion, applications frequently provide locale metadata, explicit separators, or textual month names, such as April 11, 2024. As a concept, MonatTagJahr helps describe and compare date orders across languages and software, serving as a reference point in discussions of internationalization and user input design.
