Because computation of East Asian traditional calendar depends on time when
various astronomical phenomenon occur, especially nowadays when almost all
places that are still using the old calendar have switched to use the
actual observed/predicted time for those astronomical phenomenon to occur
based on modern scientific prediction methodology, yet the time standard
being used to compute those traditional calendar differ in each regions and
there are multiple occasions in different countries that the time used to
compute the traditional calendar, do not directly correspond to the time
when the standard time were changed. Is it viable to record such
information in another region within tz database?

Having such a region could also remind vendors in East Asia area that the
world have more than one timezone when computing traditional East Asian
calendar and also remind vendors outside East Asia that there are not just
Chinese-time-based-Chinese-calendar when computing days, especially when it
come to computing festivals based on the traditional East Asian calendars
like Lunar New Year, Double Nine Festival, Winter Solstice and Mid-Autumn
