countdownjs - A simple JavaScript API for producing an accurate, intuitive description of the timespan between two Date instances

•    Javascript

A simple JavaScript API for producing an accurate, intuitive description of the timespan between two Date instances. While seemingly a trivial problem, the human descriptions for a span of time tend to be fuzzier than a computer naturally computes. More specifically, months are an inherently messed up unit of time. For instance, when a human says "in 1 month" how long do they mean? Banks often interpret this as thirty days but that is only correct one third of the time. People casually talk about a month being four weeks long but there is only one month in a year which is four weeks long and it is only that long about three quarters of the time. Even intuitively defining these terms can be problematic. For instance, what is the date one month after January 31st, 2001? JavaScript will happily call this March 3rd, 2001. Humans will typically debate either February 28th, 2001 or March 1st, 2001. It seems there isn't a "right" answer, per se.
