Patnáctná
Patnáctná is a historical Czech term referring to a unit of land measurement. It was commonly used in agricultural contexts, particularly during the Austro-Hungarian Empire and the First Czechoslovak Republic. The exact size of a Patnáctná could vary depending on the region and the specific cadastral system in place, but it generally represented a parcel of land suitable for a certain amount of agricultural work or produce. It was not a fixed, universal unit like a hectare or an acre, but rather a practical designation for land management. The term itself derives from the Czech word "patnáct," meaning fifteen, which may have alluded to a division of land into fifteen parts or a yield corresponding to fifteen units. Understanding Patnáctná is important for historical land records and understanding agricultural practices of the past in the Czech lands. Its usage has largely been superseded by standardized metric units.
