Documentation

see the Moment.js docs for different ways of formatting the date output

(in)accuracy

There is an issue with accuracy when using date.subtract(n, 'days'), which is discussed in this issue. A hardLimit has been implemented here to avoid dates earlier than June 1888, this is NOT the point at which the bug appears, it is just an arbitrary limit because for my use case i am not interested in dates older than this.
