We discussed briefly the issues with ISO Dates on the Dev List
Recently, at reboot 8, which was all about the 14th century renaissance,
there has been use of vevents to describe events that took place
hundreds of years ago[1,2].
Because hCalendar uses ISO Dates we are limited. We can't switch easily
between gregorian and julian, as well as describe BCE dates, or circa 1492.
