I am certainly not an expert on the topic, but I believe the conceptual problem can be reduced to using an input designed for a group (in the mathematical sensce) to represent a value that is torsor.

Therefore asking for a duration using <input type=number> is fine – asking for a calendar year, however, is obviously a type error. <http://math.ucr.edu/home/baez/torsors.html> -- Nils Dagsson Moskopp // erlehmann <http://dieweltistgarnichtso.net>
