Origin of the months

Fun fact time.

While in Spanish i came to the realization that the months September, October, November and December came from 7,  8, 9, 10. I knew Octo was Latin for eighth. I wondered why they were representations 7th, 8th, 9th, 10th. Well obviously I googled it when I got home and here is what I found out. The names of the month actually come from the Romans.


January
Named after the Roman god of beginnings and endings Janus (the month Januarius).
February
The name comes either from the old-Italian god Februus or else from februa, signifying the festivals of purification celebrated in Rome during this month.
March
This is the first month of the Roman year. It is named after the Roman god of war, Mars.
April
Called Aprilis, from aperire, "to open". Possible because it is the month in which the buds begin to open.
May
The third month of the Roman calendar. The name probably comes from Maiesta, the Roman goddess of honor and reverence.
June
The fourth month was named in honor of Juno. However, the name might also come from iuniores (young men; juniors) as opposed to maiores (grown men; majors) for May, the two months being dedicated to young and old men.
July
It was the month in which Julius Caesar was born, and named Julius in his honor in 44 BCE, the year of his assassination. Also called Quintilis (fifth month).
August
Originally this month was called Sextilis (from sextus, "six"), but the name was later changed in honor of the first of the Roman emperors, Augustus (because several fortunate events of his life occurred during this month).
September
The name comes from septem, "seven".
October
The name comes from octo, "eight"
November
The name comes from novem, "nine".
December
The name comes from decem, "ten".



So originally March was the beginning of the year. Who knew?
