MOST of the Months come from Roman emperors or numbers September 7 (although it's 9 now) October is 8 (but 10 now) because they stuck in August (for Augustus ) and July (for Julius) I think... Course November was 9 now 11 and December was 10 now 12.

Not sure where the days of the week came from... Druids? Saturday is for Saturn... Friday is Catholic because they always eat FRIed fish on that day !! whistle
