Hi Kangchan,

My thought on this is seperating storage from usage is the way to go.

For example, conversion functions on the ECMA date object would be
sufficient for runtime conversion between calendaring systems.

This gets more interesting when we get to recurring events. I suggest that
lunar dates can be captured in the recurence object, only that lunar based
recurrence will result in more verbose recurrence objects (i.e. converting
lunar recurrences to solar dates and storing those specific dates as part
of the recurrence object).

We still have some work to do around dates but iCalendar and vCard not
supporting lunar dates is telling..and I don't believe that's an oversight
on their part - rather that conversion is a sufficient solution.

Dear all,

I reviewed Icalendar[1][2][3], Vcalendar[4], Vcard[5][6], and there is not

Lunisolar Calendar on those specifications.
