Description Philipp 2013-10-24 00:29:10 UTC 
From the discussion on #344005 it seems to me that this would be on-topic for GDateTime.

I have a user request (in bug #530668) to show the chinese lunar calendar in the clock. The user sent a patch to use liblunar ( http://code.google.com/p/liblunar/ ), which seems to provide a GtkCalendar-like interface adapted to show the lunar calendar. Vuntz and Behdad argued in 2008/2009 that this would be more on-topic for GDateTime, which I'm inclined to agree with.

Please let me know if you agree.

GDateTime is not the right place for this: its documentation and API is already pretty specific in defining it as based on the Gregorian calendar:

    GDateTime is a structure that combines a Gregorian date and time into a single structure.

what we need is a GCalendar API that allows transforming times and dates in different calendars into GDateTime.

GLib won't depend on an external library either.

potential prior art:

Cocoa: https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSCalendar_Class/Reference/NSCalendar.html#//apple_ref/occ/cl/NSCalendar

Qt:
does not have relevant API

Windows:
there's API in the locale to get the calendar, but I haven't found any date transformation API; admittedly, I haven't been looking for long.

this is really a duplicate of bug 344005.
