Could we perhaps make the functions which do date calculation and
differencing pluggable? That is to say, we expose them on the DOM of the
widget, so you can do:

function gervsSubtractDates()
{
  ...
}


myWidget.subtractDates = gervsSubtractDates()

That way, you could have a calendar widget that defaulted to Gregorian
but could be hacked by specialist web pages to display other sorts of
calendar.

Note I haven't thought this through very well - it may be rubbish :-)
