I think I'm going to have to withdraw my offer at this time. sorry, courses just started at uni, I haven't felt very well lately and I seem to be slipping into another depressive phase right now. Sorry :/
there's a facebook app called the 13 moon calendar that you can use to figure out what your exact "mayan sign" is... i'd be more likely to do 'em if you guys did the work of figuring out the dates. =p
also the best site for this stuff was mayantimes.com or mayantimes.org... not up anymore but you can use the wayback machine at archive.org to view it. i often do.
