Magic,is it true ?
An English word for the twelfth month of the year, December is originally Latin and means tenth month. December was the tenth month of the Roman calender at the time the name was coined
Attributed to Romulus,the Roman calendar originally was determined by the cycles of the moon and the seasons of the agricultural year. The calendar then was nominally ten months long (304 days), beginning in March in the spring and ending in December with the autumn planting. Indeed, one still can recognize the remnants of this early calendar in the numbered names for Quinctilis (July), Sextilis (August), September, October, November, and December. Six months had thirty days and four had thirty-one. The winter months were not counted because there was no agricultural work then.
