Bib, Maverick, like I said, it is quite easy to reconcile. Just because one calendar is dominant in the GFFA, does not mean that one calendar is used for everything. The official, government standard calendar has 10 months. It is the calendar used for legal documents and in many social conventions. However, for some things, other calendars are sometimes used. In this case, it is a lunar calendar for describing Leia/Mara/any other woman's pregnancy. This is not so difficult to accept. Here on Earth, there are several different calendars in use today. The most common is the Gregorian calendar. However, there is a separate Jewish calendar (lunar-based numbering years from the time of the Exodus), a Chinese calendar, the old Julian calendar. The Aztecs used another calendar that is still used in some villages in Mexico. Don't forget the Mayans, Olmecs, Egyptians and other societies that have existed in just the last 4000 years.
