Hello Peter,
As per my understanding you want to convert Georgian timeseries calendar to lunar calendar (Chinese). Although you can convert Georgian calendar to Persian and Islamic lunar calendars, from my understanding there is no function in MATLAB that can directly convert it to Chinese lunar calendar. To know more about the conversion mentioned above please go through this documentation page:
Instead, write an algorithm yourself to convert to lunar Chinese calendar. Please go through this GitHub page to learn more about the algorithm:
Hope that helps,
Krishna.
