ya know, this may have been blatantly obvious to everyone else, but i just realize, while studying spanish that the days of the week were named after the planets/heavenly bodies in our solar system..
its a lot easier to see it when you look at the spanish name.

monday/lunes - luna = moon

tuesday/martes - marte = mars (twin to earth?)

wednesday/miercoles - mercurio = mercury (hermes was the greek name...?)

thursday/jueves - júpiter = jupiter (i wonder if thur- has anything to do with thor, the greek name for roman jupiter)

friday/viernes - venus = venus

saturday/sábado - saturno = saturn

sunday/domnigo - sol = sun (ok. maybe that one is easier in english. i have no idea what domingo pertains to. maybe some gay saint.)
