I have no time to follow the discussion you are talking
about, but...
While making date syntax more general please remember
that there are other [[calendar]]s in usage around the world nowadays,
not only Western invention (ie. [[Gregorian calendar]])
The number of [[Islamic calendar]] + [[Chinese calendar]] calendar
users
is quite impressive.

I will remember that only once Islamic or Chinese (or Jewish or Mayan or
French Revolutionary or Discordian) dates are actually used on
Wikipedia.
