Forum:KB:GrS vs BBY/ABY

I gather that the standard BBY/ABY calendar uses a 10-month system–longer months than in real life, with the odd holiday week or day thrown in here or there to make the span of an entire year roughly on par with a real year (I believe it works out to 368 days for the Coruscant year, correct?)

So I'm trying to sort through Clone Wars era stuff, and there's a lot of sorting particularly on the individual year pages (ie: 22 BBY) that are done by GrS months. But I see on the 22 BBY page that there are 11 months on the GrS calendar. Worse, on the 21 BBY page, there are 12.

I don't own any of the reference books that might explain this, and the articles here are not especially clear; so could someone please clarify this for me? are there 12 months per year by the GrS calendar? And, if so, are they shorter months (like real-world months) so that the two calendar styles don't get 2 months out of sync with each passing year? Thanks. – DigiFluid 18:07, February 25, 2012 (UTC)
