C'est le premier étage du Paléocène, première époque du Paléogène, dans l'ère Cénozoïque (Tertiaire) ; d'après le calcaire zoogène danois (calcaire de Faxe, près de Copenhague).

Paris, Technip.)"@fr, "The Danian is the oldest age or lowest stage of the Paleocene Epoch or Series, of the Paleogene Period or System, and of the Cenozoic Era or Erathem. The beginning of the Danian (and the end of the preceding Maastrichtian) is at the Cretaceous–Paleogene extinction event 66 Ma. The age ended 61.6 Ma, being followed by the Selandian. Close to the end of the Danian, around 62.2 Ma, occurred a hyperthermal, similar to but smaller in magnitude compared to the more famous Palaeocene-Eocene Thermal Maximum (PETM), known as the Latest Danian Event (LDE). The event, which took place over a 170-230 kyr time interval, is evidenced in the geologic record by two negative carbon isotope excursions and is believed to have led to a 2–3 °C (36–37 °F) warming of both deep and surface seawater. This hyperthermal also led to a shallowing of the oceanic lysocline, as evidenced by the significant decrease in calcium carbonate preservation.
